InrnooucrloN

A variety of pavement markings and markers are presently being used by municipal agencies and

the Nevada Department of Transportation (NDOT) on the roadways within their appropriate

jurisdictions in Clark County, Nevada. Examples of types of such markings include lane

markings, stop bars at intersection approaches, and pedestrian crossings. The materials used for

such purposes include paints, epoxy, tapes, thermoplastics, and raised pavement markers. These

pavement markings are critically important in facilitating orderly traff,rc operations, both

pedestrian and vehicular, as well as for maintenance of safety on the roadways. Over the years, a

rapid deterioration of the pavement markings on roads ín Cla¡k County has been observed. This

has translated into significant safety, operational, maintenance, and financial concems for the

agencies responsible for their maintenance. This report documents the efforts, results, furdings

and recommendations of a study conducted by the University of Nevada, Las Vegas (LJNLV)

Transportation Resea¡ch Center (TRC) for the Clark County the Regional Transportation

Commission (RTC) to address issues related to the existing specifications and the performance of

pavement ma¡kers and markings on roads in Clark County.

The study conducted by the TRC evaluated the performance of pavement marking

materials and their specifications used on roads in Clark County. The report documents product

specifications for pavement marking and marker materials and procedures that are presently used

by Clark County, NDOT, local municipal agency and industry standa¡ds. Further, it documents

issues and problems of the materials used as well as the functional lives of these materials as

reported by the various agencies. The pavement marking materials considered include paint, filn¡

thermoplastics, and raised pavement markers. It is expected that the outcome of this project

would enable the RTC, NDOT and local municipal agencies in Clark County to develop a product

list that would meet the desired specihcations. In order to help the agencies in this regard, the

report identifies a set of suitable standardized tests and procedures that can be used for product to

help develop a product lists of pavement marking / marker materials and manufacturers / vendors

that meet the desired performance standards and specifications. This document is the final report

for the project. The following is a discussion of each of the tasks caried in the project.

T¡,sx I-1 IoTNTTNTCATION ¡.NN EV¿.T,UATION OT EXTSTTNC M¡.TNRIAL

SpBCTTIC¡,TIONS

Wittrin the geographical boundaries of Clark County there are many different agencies that are

responsible for the construction and maintenance of roads in their respective administrative

jurisdictional areas. These agencies, which include Clark County, City of Las Vegas, City of

North Las Vegas, City of Henderson and Boulder City, all generally follow the specifications for

pavement markings set forth by the Regional Transportation Commission (RTC) [1]' The other

agency, the Nevada Department of Transportation (NDOT) has its own set of specifications [2].

Copies of selected sections of the specifications are included in the Appendices A and B.

Both the NDOT and RTC specifications precisely dehne the requirements for the desired

physical properties and material compositions that make up a pavement marking material. They

def,rne properties such as tensile strength, bead content, etc.. The specifications also identify the

tests to be used to check for adherence to these specif,rcations. However, they do not deltne

explicitþ the desired performance criteria for the materials when in service. The specif,rcations

mention performance indicators such as skid resistance, reflectance, and color, only in terms of

their initial values, and not when they have been placed in service. The potential existence of the

correlation between the materials' laboratory properties and their performance in the field appears

to be the main justification for the specifications emphasizing material compositions and

laboratory properties, as opposed to direct specifications for field performance. The other reason

may be the desire by the agencies to avoid additional costs of equipment and personnel that would

be needed for held monitoring and measurements of marking materials in service.

The following is a paragaph from the RTC specifications [1] (section 714.03.06 (a) and

(b)) defining the field performance requirements for Types I and2 pavement marking films:

"The frlm, when applied according to the recommendations of the manufacturer, shall

provide a neat, durable marking that will not flow or distort due to temperature if the

pavement surface remains stable. The film shall be weather resistant and, through normal

traffrc we¿r, shall show no fading, lifting or shrinkage which will significantly impair the

intended usage of the marking throughout its useful life and shall show no significant

tearing, roll back or other signs of poor adhesion"

This specification clearly leaves a lot of room for several interpretations for quantification

of the performance properties such as fading, shrinkage, and adhesion. It does not provide clear

2

guidelines for the agencies to have a consistent and objective way of evaluating the perforrnance

of the materials and determining if and when they fail. With respect to service lifetimes, it appears

that the current practice with most agencies is to use the vendor's warranty period as the desired

service lifetime for the materials.

There is, therefore, a need to enhance the performance criteria in the specif,rcations. For

example, the specifications could qpecify a more explicit minimum "sewice life" for a material

under given traffic and pavement conditions. The "service life" could be defined in terms of the

material's deterioration in performance indices such as reflectivity, color, and adherence to the

surface. The specifications could further define a monitoring period, such as six months or one

year, over which installed materials would þ monitored for performance and appropriate

measures to be taken in case of premature failure of the materials.

T¡.sr I-2 ASsnSSvrnNT AND QUINTTTTCATION OF ExISTINç PROBLEMS çITHP¡.vrcn,TpNT MARKING MATERIALS

This task includes assessment and quantification of the nature and magnitude of existing

problems with the pavement marking materials on Clark County roads. In order to

accomplish this task, information was sought from representatives of all the public agencies

responsible for the construction and maintenance of roads in the county. Representatives from

each agency were identified in consultation with RTC staff. A complete list of all representatives

is provided in the Appendix C.

A survey instn¡ment (Appendix D) was developed for this task. It consisted of a

questionnaire requesting information from the representatives on the different types of pavement

marking materials and vendors each agency uses and their views on the performance of each

material. Tables 1 to 4 provide a summary of the responses from the written survey. The

information on the written survey was followed-up by a second telephone survey. Both the raw

responses from the written survey and the telephone interviews are included in the Appendices E

and F respectively. The following is a brief discussion, by type of pavement marking material, of

the findings from both surveys.

3

Raised Pavement Markers

From the responses (Table I ), it appears that raised pavement markers last longer than all the

other materials. They reportedly last from I to 10 years with what seems to be an average of 5

years. The representative from the Cify of Las Vegas believes that raised pavement markers are

more suited for this area than the other materials. However, NDOT reported a service life of only

one year, which could probably be a result of the high volumes of ffaffic on NDOT-maintained

roads. There are several other factors that may influence this difference in reported service

lifetimes. These factors will be discussed under Task I-3.

One of the common problems with raised pavement ma¡kers appears to be that they often

break or sink into the pavement. The markers may also slide or move on the pavement. A

summary of the typical problems with the ma¡kers as reported by the agencies is presented below:

Cracking: Markers crack before they were expected to.

Sinking: Ma¡kers sink into the pavement.

Displacement: Ma¡kers get displaced and move out of their originally installed locations.

Retroreflection: Pre-mature loss of reflective properties of the markers.

Tape Pavement Mørkings

In general, tape pavement markings do not appeil to last as long as raised markers (Table 2).

They reportedly last between 6 months and 5 years, with an average of 3-4 years. As with raised

markers, NDOT reported shorter lifetimes of 6 to 12 months. The general opinion for most

agencies is that these materials do not last as long as thoy should. As a result of their poor

performance, Boulder City has reportedly not used them for sometime now. Their representative

believes that tape is generally not a suitable pavement marking material for the hot dry climate this

area is subjected to.

The tape pavement marking materials generally tail due to both reflectivity and adhesion

problems. With respect to reflectivity, tape markings often get covered with dirt and road grime.

As a result, they "blacken" up,loose thei¡ reflectivity, and become very difficult to see. Tape also

often moves and tears from the pavement due to the shear forces it is subjected to. These two

problems a¡e summarized below:

Shearing The tape gets ripped or tom and the pieces scattered through the intersection.

4

Dirt The grime from the roadway would blacken up the tape, affecting its reflective

properties, and making it less visible to drivers.

P aínt P av e me nt M arking s

It appears that most agencies are relatively satisfied with the performance of the paint marking

materials (Table 3). Paint pavement markings have the most consistent performance with respect

to durability and performance, even though they last the shortest amount of time. Paint markings

last from several days to 2 years, with an average of 6-12 months. Paint markings typically fail by

loosing their color and by wearing out. Like tape, paint markings get covered by dirt and road

grime, and subsequently become diff,rcult to see. Thus, the single most common problem for paint

pavement markings is:

Dirt The dirt and grime from the roadway blackens up the paint markings and makes it

less visible. This affects the reflective property as well.

T he rmoplastíc P av e me nt M arking s

Only two agencies, City of Las Vegas and NDOT, responded about this type of pavement

marking material. Their responses (Table 4) were very different and could not be generalized.

The City of Las Vegas, reported that the thermoplastic pavement markings last between 3 to 8

years, while NDOT reported shorter lifetimes of only 6 to 12 months. The ma¡kings have the

same problems as tapes, namely, shearing and dirt, as described above under tape. The City of

Las Vegas reported reflectivity problems also due to insufficient beads in the material.

In conclusion, it should be noted the service lifetimes reported above for the different

pavement marking materials are based on subjective evaluations. At present, there appears to be

no consistent and object way that the agencies can determine when a pavement material has

reached the end of its service life. Therefore, some of the differences in the lifetimes reported by

the agencies could be attributed to the different criteria the different agencies use in determining

when a material has failed functionally.

Another potential reason for the differences in reported lifetimes are the different vendors

supplying the materials to the different agencies. The survey shows at least one case where

agencies using the same vendor report simila¡ relatively lower service lifetimes.

¡,No R¡¡sno Mnmnns

A discussion of some of the main causes of the problems with pavement marking materials

presented in Task I-2 is presented in the following sections.

Higher volumes of trafJîc and poor installation

These two factors are common to all types of materials. Both contribute to faster deterioration,

and hence shorter service lifetimes, of the materials. This is partly evident from the fact that

NDOT, whose roads generally carry heavier traffic volumes, reported the shortest lifetimes for all

the materials. Poor installation also is a major cause of poor performance of the materials.

Materials installed at wrong temperatures, or on dirty (or improperly prepared) surfaces are not

likely to last very long. An offrcial from the City of Phoenix, Arizona, also reported problems on

markings installed on new asphalt pavement surfaces [3]. Other possible reasons specific to each

type of material are discussed next.

Røis ed P av e rne nt M arkers

Heavy axle loads (e.g., loaded tnrcks) and large numbers of repetitions of such loads cause high

levels of stresses on the ma¡kers causing them to crack or break. Such stresses also often move

the markers from their intended locations. In addition, when asphalt concrete pavement gets

extremely hot and becomes soft, the ma¡kers often sink into the pavement when subjected to

heavy wheel loads. All these reasons affect not only the durability of the markers, but also the

refl ectivity properties.

Another problem with raised pavement markers is when asphalt bleeding gets tracked on

to the markers, darkening them and resulting in loss of reflective properties. Reflectivity appears

also to be affected by intense solar insolation, much like the kind that this area experiences in the

summer

T ape and T he rmoplastíc P aveme nt M arkings

Tuming movements create shea¡ forces that exceed the shea¡ strength as well as the tensile

10

strength of the materials. This can tear the material and move the torn pieces across the

pavement. One potential solution to this problem was put forward by the representative from

North Las Vegas, who suggested that perhaps the tape markings should be inlayed into the

pavement. This would reduce the shear stresses that the markings are be subjected to and may

result in longer service lifetimes. However, that may lead to a more expensive installation

process.

The other problems with tape and thermoplastic pavement markings are due to

accumulation of dirt and grime on the markings. These are particularly acute problems in this

area because of excessive dust and lack of significant or regular precipitation to wash off the dirt.

P aint P av e me nt M arkings

Simila¡ to tape and thermoplastic pavement marking materials, the dry climate in this area make

dirt and road grime a particularly acute problem with paint markings. There is no signif,rcant or

regular precipitation to wash-off the dirt and road grime over the paint markings.

Tmr I-4 InnnnrrcATloN oF EvALUATToN Cnrrnnr¡.

performance of the ma¡king materials can be evaluated based on the following performance

properties. These performance measures have all been specified in both the NDOT and RTC

specihcations. They have also been used in several national test decks run by AASHTO's

National Test for Product Evaluation Program (NTPEP) for testing of pavement marking

materials and raised pavement ma¡kers [4].

Durabilþ

Durability is a measure of the resistance of the marking materials against wear. With respect to

pavement marking materials, it is typically measured in terms of the percent material remaining on

pavement surface. It is a field test carried out according to ASTM D 713. For raised pavement

markers, durabiliry is measured by the proportion of raised markers retained at their originally

installed locations. Broken or othenrise defective markers will not be counted as retained

markers even if they are still at their initial locations.

l1

VisíbilitylColor

This is a measure of the "brightness" of each stripe of a pavement marking material. It is also a

measure of how much the material is able to retain its original color, and it is typically a measure

for daytime visibility or effectiveness of the markings. The parameter can be measured using a

colormeter that measures how white or yellow the material is. Alternatively, the parameter can be

measured subjectively by a team of raters who inspect the marking materials and give a subjective

rating of the "visibility" of the material.

Retroreflectívíty

This is a field measurement for nighttime visibility of the marking materials and raised pavement

markers. It is normally measured in the field using special equipment such as the Mirulux, the

LTL2000 or other similar equipment. However, for raised pavement markers, retroreflectivify of

the markers can also be measured in the laboratory by taking field samples of the markers to the

lab for measurement.

Skid Resístønce

Skid resistance is a measure of the friction between the pavement marking and the vehicle's tires.

This is measured with a British Pendulum Friction Tester and is tested in accordance with ASTM

E 303. It is important to guarantee a safe driving surface and it is to help ensure that the driver

will not lose control when braking or turning on a pavement marking. Current specihcations call

for a minimum skid resistance of 45 to 55 BPN (British Pendulum Number)'

T¡.sx I.5 TNSIS FOR EVALUATION OF PERFORMANCE P¡.N¡UTTNNS

Having identif,red the properties to be measured, this task identified the tests to be conducted for

evaluation of the identified properties. Most of the materiel presented here is adopted form

cunent literature such as various NTPEP reports on several test-decks conducted across the

nation. This section identifies and presents the laboratory and/or field tests that wiil be conducted

in order to evaluate the desired properties and performance measures identified in the previous

t2

task. Equipment needed to conduct these tests will also be identified and their costs estimated.

The field tests for evaluating pavement marking materials will be based on the various ASTM and

NTPEP tests as described next.

A. Field Tests For Pavement Marking Materials (such as paints, tape, thermoplastic, etc.)

There are several field tests to be conducted on pavement marking materials such as paints, tape

and thermoplastics. The tests are described next.

Color

This test is for measurement of visibility of pavement marking materials. Specialized

equipment, such as the BYK-Gardner Color Guide is used for the purpose. The readings will

be compared with Standard Highway Colors using CIE chromaticity coordinates for white,

and yellow markers. Applicable test procedures include ASTM E 308 and ASTM E 1349.

Retroreflectivity

Readings with a Mirolux Retroreflectometer or equivalent equipment with similar properties

shall be made within seven (7) days of the application and each rating period. This would be

measured in accordance with ASTM D 4061.

IdentiJícation of Reasons for Perfonnance Deteríoratíon

Associated with the two tests mentioned above, subjective determinations will be made for

each case to identify the possible reasons for deterioration of performance of the marking

materials. Potential reasons include worn-out or drrty markings, loss of beads, general fading.

Percent Remaining (ASTM D 713)

This test measures the proportion of the surface area of the marking is still remaining on the

pavement at the original location. It is a subject test that provides an indication of the

durability of the marking material. Normally a rating scale of 0 to l0 is used, with 0 indicating

that the material is almost or completely gone, and a 10 indicating that l0Ù7o of the material is

l3

still attached to the pavement. The measurement is based on averaging the ratings (or scores)

of a team of raters, each making subject (and independent) determinations of the percent

remaining.

In conjunction with the durability measurement, a determination will be made

regarding the failure mode. Potential failure modes include:

o abrasion failure, caused by shear and other forces as a result of traffic flow (includes

displacement of ma¡king due to the shear forces)

o stripping failure,caused by the pavement, for example as a result of pavement cracking or

pavement shoving

. bond. failure, clean separation of the marking material from the pavement caused by loss

of adhesion to the Pavement

Either the predominant mode of failure, or proportional distribution among different failure

modes may be identified for each marking.

Skí.d Resístance

The skid resistance of a marking will be measured in accordance with ASTM E 303. This test

will use an apparatus called a British Pendulum Friction Tester.

B. Fietd Tests For Raised Pavement Markers

There are two types of raised pavement markers, reflective and non-reflective ma¡kers. The

reflective markers will be evaluated for both durability and night visibility, while the non-reflective

ones will be evaluated for durability only.

P e rc e nt M arkers Retaíne d

As mentioned in Task I-4, this test is a measure of durability of the raised markers.

Observations will be made by counting the number of markers retained on the pavement at

their originally installed locations relative to the total number of markers initially installed.

Broken or otherwise defective markers will not be counted as retained even if they are still in

place.

t4

In conjunction with this durabiliry test, reasons or modes of failure will be identihed

and recorded. Typical failure modes for raised markers include:

o breakage or cracking of the ma¡kers (at originally installed locations),

o pavement failure (a marker coming out with a chunk of the pavement),

o adhesive-pavement bond failure, and

o marker-adhesive bond failure.

Retroreflectívíty

Retroreflectivity for raised markers can be either be measured in the field using a portable

retroreflectometer, or in the laboratory.

T¡.sx I-6 Snr,ncrroN oF TEST Loc¡.rroNs

A survey of all participating agencies was conducted to help identify potential sites for the test

decks. Locations were identified by each agency and classihed by level of ADT, truck flow per

day, number of turning movements, and by pavement type, i.e., asphalt concrete surface (new or

old), or rigid pavement surface. The results of the survey are presented in Appendix K. The exact

number and locations of the test sites are to be determined as a part of the field testing and

evaluation efforts.

T¿,sx I-7 InnNrrrrcATIoN Or M¡.tluFAcruRERs/ VENDoRS

A list of manufacturerlvendors who could be invited to participate in the field testing and

evaluation project has been compiled. It is presented in Appendix H. This list is based on

information obtained from the participating agencies and from some of the NTPEP reports. If

necessary, additional manufacturers / vendors may be added to this list upon recommendation by

the RTC. Once the Work Plan for field testing and validation is approved, each of the vendors

will be notified by a letter sent by the RTC which will formally invite them to participate in this

project.

Part 1: Pøvement Mørkíng Materials (Exclading Raised Markers)

Introduction

The purpose of this task is to provide an outline of the procedures for testing and evaluating

pavement marking and ma¡ker materials. The procedures follow the standard evaluation

procedures developed by the NTPEP [4]. The study task will be performed at appropriately

scheduled times and the test results made available for use by participating agencies. Short life

products, such as paints, will normally be evaluated only during the first year, while longer life

products, such as thermoplastics, will continue to be evaluated through the second year on a four

(4) month cycle.

The Field Testing Procedures are generally in accordance with ASTM D 713,

"Conducting Road Service Tests on Fluid Trafflrc Marking Materials." The use of a Mirolux

Retroreflectometer, or equivalent equipment for measurement of retroreflectance, will be used in

lieu of the night-time visibility evaluation. Evaluations will be conducted approximately every

thirty (30) days for the hrst four months, every sixty (60) days for the next eight months and

approximately every one-hundred twenty (l2O) days during the second year on longer life

materials. Appearance and durability data will also be collected. This field data collected will

subsequently be used to obtain estimates of the length of the useful lives of each material.

Materials criteria

The study will look at both liquid and pre-formed marking materials. These will include epoxy,

methyl methacrylate, polyester, polymeric films, tapes, thermoplastics and paints. Materials

submitted for held testing shall be those accepted for this purpose by the RTC's Operations

Subcommittee. Laboratory test samples of sufFrcient quantity shall be extracted from the material

prior to field application and provided to the project team'

Two options are available for carrying out the laboratory tests. One option is to set up an

in-house capability at UNLV TRC or another local agency to perform these tests. The second

t6

option is to have manufacturers/ vendors test their materials at an approved independent

laboratory and submit certified results to the project team. The f,rrst option could cost more in the

short run, but has the distinct advantage that the laboratory so established can be used for future

testing of materials. Thus, this could be more cost effective in the long run. It is recommended

that the hrst option be pursued, but that recognizing the fact that setting up the in-house

laboratory would require some time, require the manufacturers / vendors to also submit certified

results from an approved laboratory. It shall be the responsibility of the manufacturers / vendors

to send their materials to approved independent laboratories for testing of the materials and to

submit certihed results to the project team prior to the material being accepted for field testing.

Only materials that satisfy all laboratory test criteria shall be approved for held testing.

Test Decks

Field test decks on both portland cement concrete (PCC) and asphalt concrete surfaces (AC) shall

be evaluated. There will be two types of test decks. The hrst one will consist of test stripes for

testing materials for longitudinal markings, such as lane markings. The decks shall be selected

using the guidelines of ASTM D-773,which recommends selecting sections where traffic is heavy

(minimum ADT 10,000), free-rolling with no grades, curves, intersections or access points near

enough to cause excessive braking or tuming movements, where wear is uniform with full

exposure to the sun throughout daylight hours, and areas which have good drainage' Each

material shall be tested at three different sites to ensure system redundancy in case of unforeseen

problems at the test sites. This is essential to obtain reliable results from the tests and evaluations.

The second type of test deck will consist of test stripes for testing materials designed for

transverse markings, such as stop bars, pedestrian and railway crossing markings. These test

decks shall be located at selected intersection approaches and at-grade railway crossings.

However, since there are relatively few at-grade railway crossings in Clark County, no test decks

are proposed at these sites.

Selected pavement surfaces shall be representative of the pavements upon which the trafflrc

marking materials will be applied in practice. The following sets of test decks will be used as

described below

t7

l. Three test decks at different locations will be set up and test lane markings installed for testing

of materials for longitudinal lane makings on roadways with old AC pavement surfaces. For

purposes of this project, pavement íurfaces of more than six months since applied will be

considered old. The sites will be of similar traffic characteristics in terms of both Average

Daily traffrc (ADT) and traffrc mix. However, sites with different surface treatments (i.e.,

asphalt pavement mix) may be selected in order to obtain an indication of the effect of

pavement mix design on performance of the marking materials. Sections of the roadways with

signihcant driveway traffîc shall be avoided to the extent possible.

2. Three more test decks at different locations for testing of materials for longitudinal lane

makings on roadways with new AC pavement surface, i.e., pavement surface less than six

months old since application. The sites will also be of simila¡ traffrc characteristics and will

have the same set up as described in (l) above.

3. A¡other th¡ee test decks will be established at different locations for testing of materials for

longitudinal lane makings on roadways with PCC pavement surface. The logistics and set up

are similar to those described in (1) and (2) above.

4. Several test decks for testing pavement materials designed for use as transverse markings at

intersections. Intersections with old and new ACC pavement surfaces will be used. The

intersections will have relatively similar traffic characteristics, in terms of the volumes of

approach flows, traff,rc mix, and turning movements.

Application Procedures and Controls

On test deck sets 7, 2, and 3, four (4) stripes for each material to be tested shall be installed on

each site. The lane markings shall be installed as per existing guidelines. For example, stripes for

lane markings shall be 10' long with a 30' gap belween stripes (Figure 1). This translates to 5

stripes for each 200' of lane. A 6-lane roadway (3 lanes each way) will have will have 4 broken

18

lines dividing the lanes (total, both directions). This would result in 20 test stripes per 200' of

roadway. If there are 2O vendors each with two different materials, there will be 40 different

materials to be tested for a total of 160 stripes. The required roadway segment length of 1,600

feet for each test deck. A similar set-up would be used for the solid yellow centerlines and the

solid white edge line markings.

For test deck set 4, each test stripe at a test site shall consist of a stripe of appropriate

width of transverse marking across one approach or exit lane. An intersection with 2-lane

approach roadways and an additional single lefçturn pocket will have 52 test lines (Figure 2). For

statistical reliability of the resulrs, each material shall have six (6) test stripes at different approach

locations. This means that about 8 different materials can be tested on one such intersection.

Therefore, if, for example, there are 20 vendors each with three materials to be tested, there will

be a total of 60 different materials and seven (7) intersections will be required for each pavement

surface. This number may be vary depending on the actual number of approaches for selected

intersections, and the number of vendors and materials to be tested'

In general, the installation procedures shall be in accordance with Section 8 of ASTM D

713. The weather conditions at the time of installation shall be recorded and shall include

information such as ambient temperature, humidity, and pavement temperature. Each vendor

shall bear the cost and responsibility for installation of the materials at the sites. There are three

options that a¡e available to the vendor for insøllation of the materials. The installation can be

done by the vendor, a contractor, or one of the participating local agencies. There are relative

advantages and disadvantages for each of these options. For example, vendor installation has the

advantage of eliminating any potential performance problems due to violation of manufacturer's

recommended installation procedures. However, vendor installation may not reflect the normal

practice by agencies in installation of marking materials. In any case, the vendor/manufacturer

must certify that installation has been performed in accordance to their standa¡ds and satisfaction.

During installation and held testing of the pavement marking materials, the traffic control v/ill be

furnished by appropriate local transportation agencies where the test sites are located.

Field Test Observations and Evaluations

During the course of the field evaluation, several observations shall be made:

l. Temperature may play a critical part in the performance of the materials. Therefore, ambient

and road temperature readings shall be made and recorded during application and field testing

of the materials.

2. Dirt, moisture and chemical contaminants on the beaded line can alter the readings of the

retroreflectometer, even high humidity can cause a change in the readings. Data from selected

product lines that are affected by contamination or damage beyond normal wear may be

excluded in calculation of the value for that product. Use of ASTM E 178-94 (Standard

Practice for Dealing with Outlying Observations) will be used in determining whether an

individual value will be excluded in the calculation of the reported value for that product.

When an individual value is excluded, a note will appear in the report to indicate the

exclusion.

3. Field perfoünanæ tests shall be made within seven (7) days after application, and

approximately every thirty (30) days for the first four months, and every sixty (60) days for

the last eight months of the first year. Longer life products, such as thermoplastics, will

continue to be evaluated through the second year, approximately every one-hundred twenty

(120) days.

4. Field perfonnanæ evaluation shall be based on Nighnime Visibility (Retroreflectivity),

Appearance, Durability and Skid Resistance, as described below'

AppearancelColor

The appearance/color shall be determined by color measuring instrumentation which provides

coordinates in CIE color units which can be converted for use in both field and laboratory

applications. All evaluations shall be done using standard procedures and charts. The evaluations

shall be performed in the unbeaded areas of the test lines to minimize the effect of dirt collection,

mold growth, etc. Values that exceed standard tolerance limits shall be noted. The determination

shall be made without preliminary washing or other modification of the surface of the test lines.

The reported data shatl be evaluated by the use of ASTM E 178-94'

2r

Retroreflectivify

Readings with a Mirolux Retroreflectometer or equivalent equipment with similar properties shall

be made within seven (7) days of the application and each rating period thereafter.

Durabílíty

Each wheel path will be rated and the numbers averaged by examining the area 9 inches on each

side of the midpoint of the wheel path and assigned a percentage of marking filrn remaining (non-

exposed substrate). Ten percent of this number will be the rating assigned. Thus, a material with

no wear would receive a rating of 10. Three evaluators will rate independently and their ratings

averaged for a futal score. The evaluators will use ASTM D 913, 'Evaluating Degree of

Resistance to Wear of Traffic Paint," as a guide in the evaluation. When the percent of the film

remaining equals 3 or less, the test will be considered complete.

Skid Resistance

Skid resistance shall be measured using appropriate procedures and equipment as discussed in the

previous tasks.

Reporting

Field Evaluation results shall be compiled into a report and will be provided to the project sponsor

for distribution to all participating I cooperating agencies. This report shall include, as a

minimum, the following information.

l. Site location, including ADT, type, age and special treatment of surface material.

2. Company information, including n¿une, code, class of material, binder, color, primer (if needed

for durable markings) and indication if material contains lead.

3. A sample of the installed material to be provided by the vendor/manufacturer.

4. Application information, including equipment description, thickness, temperature of material,

relative humidiry, no track time, and type and rate of application of beads.

5. Tables of retroreflectivity data.

6. Tables of durabiliry data.

22

7. Tables of appearance/color data.

8. Tables of skid resistance.

Reports

The implementation of the field tests and results for each evaluation period shall be published in

quarterly reports. ln addition, an interim report shall be published after the first year and a final

report after the second year. These reports shall include documentation of all the performance

results for night visibility, day visibility, durability, and skid resistance. The results shall be

presented in tabular form.

Part 2: Raísed Pøvement Mørkers

Introduction

The procedures for field testing and evaluation of raised pavement markers are also based on the

NTPEP recommended procedures. Specified numbers of each type of raised pavement ma¡kers

to be tested shatl be installed at selected sites on asphaltic concrete (AC) and portland cement

concrete (PCC) pavements. Field and laboratory tests to evaluate performance of the markers

shall be performed periodically for two (2) years. It may be necessary to extend the test period

beyond the initial two years.

Materials criteria

The materials to be tested on the field shall satisfy all applicable laboratory tests as specihed in the

RTC and NDOT specifications in accordance with ASTM D 4280. Other materials may be

submitted for field testing if they are approved for this purpose by the RTC's Operations

Subcommittee. The physical dimensions of the markers, including the markers' base dimensions

and the angle between the base and the lens face shall be provided by the vendor. The ma¡kers

have to have abrasion resistant lens surfaces. This can be ascertained by doing an appropriate

laboratory test in accordance with ASTM D 4280, Section 9.2.2. The specific intensity of each

23

reflective surface will be tested in accordance with ASTM D 4280, Section 9.2. In addition,

adequate samples of each ma¡ker shall be provided to the project team to be used for each of the

following tests:

o Strength tests shall be conducted in accordance with ASTM D 4280 Section 9.3.1 for all

markers having base dimensions of lQQmm X lO0mm or greater.

o Ma¡kers shall be tested for compressive strength in accordance with ASTM D 4280, Section

9.3.2.

o For the two tests above, failure shall consist of either (l) breakage or significant deformation

of the marker; or (2) signif,rcant delamination of the shell and the filler material. The load at

failure shall be recorded.

o Adhesive bond strength shall be measured in accordance with ASTM D 4280, Section 9'1.

using an epoxy adhesive.

o Markers having a hard, abrasion-resistant lens surface shall also be subjected to lens impact

strength testing in accordance with ASTM D 4280, Section 9.5.1.

o The color of the reflective lens shall be tested in accordance with ASTM D 4280 Section 6.2'4

and the results reported as CIE tristimulus values and chromaticity coordinates for white,

yellow and red ma¡kers.

o Finally, temperature cycling tests shall be conducted in accordance with ASTM D 4280,

Section 9.5.2.

It is to be noted that these tests would require the acquisition of laboratory equipment. Each

vendor/manufacturer shall be responsible for conduct of all the laboratory tests and shall submit

certified laboratory test results of the sample of each ma¡ker type/material submitted for the field

test. As discussed in the section pertaining to Pavement Marking Materials, it would be desirable

to develop in-house testing capabilities for Raised Pavement Ma¡kers as well. Only those ma¡kers

that satisfy the laboratory test result specifications shall be accepted for field testing.

24

Test Decks

Test decks for evaluation of pavement ma¡kers shall consist of installation of longitudinal lane

markings at selected sites. A number of sites shall be selected on AC and PCC pavements based

on the ADT and volume of truck traffic. A minimum ADT of 10,000 shall be required. The sites

shall have the following characteristics:

o should not require crack sealing or patching or any surface treatment during the testing period

o generally be free ofhorizontal and vertical curves.

Installation and Field Test Evaluation

Each manufacturer / vendor shall supply all materials submitted for testing and shall be responsible

for installation of the materials at the test site. Similar to the pavement marking materials, the

vendor may choose to have the installation done by the vendors, a contractor, or one of the local

transportation agencies. In any case, the vendor shall certify that the installations have been done

to their satisfaction in accordance with their installation specihcations. The vendors/

manufacturers shall bear the cost of installation, and shall be responsible for supplying all the

equipment and labor necessary. Trafhc control during installation and testing of the materials

shall be furnished by the appropriate local transpofation agencies where the sites are located.

Retroreflective Permanent Raised Pavement Markers

Each material on a test site shall consist of installation of 100 markers on 12 meter centers on the

skip lines between travel lanes. Closer spacing may be used in case several vendors participating.

The total number of markers to be installed on a test site will depend on the number of

participating vendors and the number of marker types submitted by each manufacturer.

Non-Reforeflective Permanent Raised Pavement Ma¡kers

These will be installed in between the reflective markers in accordance with current installation

procedures. Reference markers shall be selected which will be used as controls on the test

markers. The reference markers used shall have similar profile and be both high performance and

25

low performance type. One hundred (100) reference markers will be installed at each test

installation for each type of raised pavement marker.

Testing will commence upon completion of installation and continue for a period of two

years. Observations will be made every three months. If necessary, rainfall data shall be obtained

from existing weather stations for the two weeks prior to each evaluation. The evaluation shall be

conducted in the field and in the laboratory.

Field and laboratory observations

Field observations shall be for the purpose of measuring durability and retroreflectivity of the

markers. The following data will be gathered:

o Number of markers retained.

o Reasons for failure (breakage, ma¡ker-adhesive bond failure, adhesive-pavement bond failure,

or pavement failure).

o Tracking of adhesive onto face of marker.

o ReEoreflectivity (may be measured in the field or in the laboratory).

These observations shall be made every three months. Retroreflectivity measurements

shall be made on each tenth marker. The measurements may be done in the f,reld or in the

laboratory. For field measurement, a portable retroreflectometer shall be used. In case of

laboratory measurement, appropriate laboratory equipment shall þ used and each marker shall be

carefully removed from the held by means that will not damage the marker case or lens face.

Reports

Field Evaluation results shall be compiled into a report and will be provided to all participating

agencies. This report shall include, as a minimum, the following information.

1. Site location, including ADT, type, age and special treatment of surface material.

2. Company information, including name, code, type of marker, color, adhesive used, etc.

3. A sample of the material to be supplied by the vendor/manufacturer.

26

4. Application information, including equipment description, and all other relevant installation

information.

5. Tables of retroreflectivity data.

6. Tables of percent retained.

7 . Tables of marker conditions.

Final Report

The implementation of the field tests and results for each evaluation period shall be published in

quarterly reports. In addition, an interim report shall be published after the hrst year and a final

report after the second year. These reports shall include documentation of all observed

performance results. The results shall be presented in tabular form.

Estimated Budget for Field Testing and Evaluation

Based on the project work plan described in the previous section, the following is an estimate of

the budget for the field evaluation and testing of pavement marking and marker materials.

Significant cost elements for the proposed project include labor and equipment costs. Labor costs

are driven by the minimum of test sites required and the total number of materials to be included.

The equipment costs are for held equipment and laboratory equipment. It is estimated that the

field equipment would cost approximately $4O,000 and the laboratory equipment would cost

$15,000. A list of key held equipment and their estimated costs is presented in Table 5.

Components of the labor requirements include program management, design and set up of

the test program, training, fieldwork, laboratory tests, data management, analysis of the data,

report preparation. These efforts vary over time depending on the extent of fieldwork involved,

which in turn is a function of the number of materials and sites included in the test program. A

summary of the labor efforts required for the held work is presented in Tables 6, 7 and 8 for

intersection test decks, longitudinal test decks for markings, and test decks for raised pavement

markers respectively. The total labor efforts amount to about 3 person years of effort over the

27

duration of the project. The labor includes efforts by an undergraduate student, a graduate

student, a professional staff member and two faculty members.

The toral budget for the proposed project is $230,372. The project budget is presented in

Table 9.

Analysis of Benefits for the Proposed Project

The proposed project budget (9230,372) is a significant commitment of resources. But, an

analysis of the tangible benefis indicates that the potential payoffs from the project greatly

outweigh the costs. The results of the analysis are telling. Even with as small an increase of 5

percent in life of the marker and ma¡king materials (whose useful life is 8 years), the net reduction

in costs over 8 years is about $636,000. But, if initially the useful life were only 4 years, the same

5 percent increase in useful life results in a reduction in cost of $1.27 million over a 8 year period.

Similarly, if the useful life were only 2 years, the 5 percent increase in useful life results in a

reduction in cost of $2.5 million over a 8 year period. Greater increases in the useful life resulting

from the project lead to even more significant reduction in costs. An analysis of various scenarios

is summarized tn Figure 3 and in Table 10. A brief description of the analysis follows.

The extent of the roadway network in Clark County was estimated based on a street

network coverage obtained from the Clark County Geographic Information Systems Management

Offrce using a Geographic Information System (GIS) program. This was further delineated by

jurisdiction (municipal and NDOT maintained roads). The extent of the road network with 4 or

more lanes was estimated and termed to be "major" roads. This ranges from 5 percent for

Boulder City to 45 percent for NDOT. It was assumed that the markers and ma¡kings on these

major are followed the existing design guidelines for Clark County. Assuming that each of these

major roads only had 4 la¡es (two in each direction) and used raised pavement markers for center-

line and lane dividers, and a 4" thick white line for edge lines, the quantities of markers and

markings in the longitudinal direction (i.e., no crosswalks, or other transverse markings are

included in this).

Installation costs of raised pavement ma¡kers and ma¡kings were obtained from bid

documents for a roadway improvement project submitted to the County in 1997. This

information was combined with the quantities of markers and markings in the longitudinal

direction to estimate thei¡ installation costs on the major roads. This was identified to be $8,867

per centerline mile of roadway. Combining this with information with the extent of major

roadways in Clark County, the total installation cost of the ma¡kings and markers is calculated to

be about $13.3 Million.

Using this information a number of scenarios were analyzed to examine the implications of

va¡ious useful lives of the materials and potential increases to the same as a result of the proposed

project. Three scenarios were designed where the useful life cycle of these markers and markings

was assumed to be 2 yean,4 years and 8 years respectively (which is consistent with the data

obtained in the survey of the local agencies - see Tables I to 4). The other scenarios are based

on the proposition that the proposed project will to help develop specif,rcations for the materials

that increased the useful lives of the materials. The scenarios analyzed in this respect considered 4

such scenarios of increases in useful life: 5 percent, 10 percent, 25 percent and 33 percent. A

period of 8 years was considered to illustrate the costs for maintaining the markers and markings.

It is to be noted, that this analysis did not account for any transverse markings or matkers,

or any markings or markers on roads that have fewer than 4 lanes. Thus, the proposed project

does indeed have the potential to lead to extemely high reductions of costs. Therefore, costs of

35

the project would be offset by these reduced costs in far less than the 2 years duration of the

project. Other intangible benefits of the project include the payoffs from utilizing the equipment

by students in their educational programs at the undergraduate and graduate levels at UNLV.

This would not only help enrich their educational background, but it will also help develop better

prepared students to enter the workforce.

CoNcr.uuNG REMARKS

One of the main objectives of this project was to identify and document problems related to

apparent pre-mature failure of most pavement markers and marking materials on Clark county

roads. Several local agencies with jurisdiction over the roadways in Cla¡k County reported

lifetimes of these materials that were in general less than satisfactory. This report documents

findings from the efforts undertaken to identify existing product specifications used by the various

agencies in Clark County, the materials used, issues and problems with the performance of the

materials including actual functional life cycles of the materials. A wide range of useful lives of the

materials has been reported by various agencies. There exists the potential for significant benef,rts

if the useful lives of the materials can be increased. One mechanism to accomplish this would be

to develop a list of materials that have the desired performance. This requires the conduct of field

testing and evaluation of materials to be considered in developing such a list.

A work plan has been developed to conduct laboratory and field tests for the purpose of

evaluating the performance of several different raised pavement markers and marking materials.

These materials would be supplied and installed for field testing by participating

vendors/manufacturers at their own cost. The tests would be carried out on both types of

pavement surfaces, asphalt concrete (ACC) and portland cement concrete (PCC). Analysis of the

test results will help identiff suitable materials that satisfy relevant local and national performance

standards and specifications for future use in Cla¡k County. As a result of this effort, materials

that are likely to have longer useful lives may be identified and an updated product list of

preferred vendors/ manufacturers obtained.

The testing and evaluation of the materials is estimated to cost 9230,372. This includes the

labor required for field measurements, purchase of f,reld and laboratory equipment, analysis and

Appendix F

Summary of Telephone Survey Responses for Performance Information

Summary of Phone Surveytt-3-97

The original survey did not produce enough information so a phone survey was conducted.

The information gathered is summarized below.

Do you follow RTC Specifications?

All of the respondents except for NDOT said that they use the Uniform Standard

Specifications for Public Work Construction put out by the Regional Transportation

Commission. NDOT mentioned that they use their own specifications, Standard Specifications

for Road and Bridge Construction.

Why do pavement markings last at such inconsistent rates?

Each of the different types of pavement markings are listed below with a suflrmary of the

responses.

Raised Markers

Most of the respondents mentioned a majority of the problems with the raised pavement

markers are due to heavy traffic, especially truck traffic. They indicated that these high load

trucks in high volumes cause the markers to either crack or become buried into the pavement.

Two of the respondents mentioned that the installation of the markers is a problem as well.One of the respondents believes that a close and more detailed inspection would produce a

better performing marker.

One of the respondents believed that raised markers are better for this area because the do notneed to be cleaned in order to be effective.

Tape

Most of the indicated probems with turning movements shearing the tape at crosswalks and

stopbars. One respondent offered a solution to the shearing problem. He mentioned thatinlaying the marking into the pavement would help reduce the effect of shearing. Inlaying is a

process where the portion of the pavement where the tape will lay is cut to a specified

thickness so that the marking wilt fit into the pavement. They also indicated problems with the

application of the tape. One respondant again mentioned that closer inspection of the

installation would reduce this problem.

Another problem that the respondents mentioned is how the marking becomes covered withdirt and grime. This will make the marking less visible and less effective.

Paint

All of the respondents mentioned that paint,lasts the least amount of time. This, however,

does not mean that paint does not last at inconsistent rates. The respondents had no

complaints with the inconsistency of these pavement markings. The did mention that dirt and

grime will cover up the paint similar to tape.

Thermoplastic

The respondents that used thermoplastic said that it has the same problems that tape has, shear,

dirt and application.

Does the manufacturer quote any performance standard and do they adhere to them?

Most of the respondent said yes and when they don't, they usually replace them before the firstyear is over.

One of the respondents indicated that it is very difficult toget the manufacturer to fix theproblem due to the fact that there is no convienent record of who was contracted to place themarking.
