Executive Summarv

The primary objective of this project is to perform field evaluations of pavement marking

products and identify those products that meet the performance criteria as specified and include

them in the qualified product list (QPL) maintained by the Regional Transportation Commission

(RTC) of Southem Nevada. Th¡ee types of products a¡e evaluated based on their intended usage:

intersection markings, longitudinal markings, and raised pavement markers (RPMs). This report

presents details of the test deck and results of the second set of field measurements for

retroreflectivity, color, and durability taken in July 2004 on the intersection and longitudinal

products. The results of the first set of retroreflectivity field measurements for RPM products,

immediately after installation in June 2004, are also included in this report.

Products for intersection markings are installed at three selected intersections in the Las Vegas

Valley. Products for longitudinal markings ,üere installed on a section of the eastbound Desert

Inn Super-arterial. RPM test deck products were placed on Durango Drive between Sahara

Avenue and Desert Inn Road.

In general, each installed product is intended to provide a marking that will not distort due to

temperature if the surface of the pavement remains stable. The intersection and longitudinal

products are evaluated based on retroreflectivity, durability, and color. Measurements of these

parameters on each product at each location are taken once every three months for one year for

intersection markings, and two years for longitudinal markings. Field measurements for

retroreflectivity and durability are taken for each RPM product at approximately three-month

intervals.

Retroreflectivity and chromacity readings have dropped dramatically for almost all longitudinal

and intersection products since installation. A few of these products are close to falling below

RTC's QPL specifications. Durability measurements for intersection and longitudinal products

have all been 95 percent or higher, with the exception of two products from the same vendor.

Since subsequent measurements for RPM products have not been taken since installation, a

preliminary evaluation will be included in the next report.

L Introduction

The primary objective of this project is to perform field evaluations of pavement marking

products and identify those products that meet the performance criteria as specified and include

thern in the qualified product list (QPL) maintained by the Regional Transportation Commission

(RTC) of Southem Nevada. This list is used by the va¡ious local transpofation and public works

agencies. Three types of products will be evaluated based on their intended usage, i.e., products

for intersection markings, products for longitudinal markings, and raised pavement markers

(RPMs).

This report presents details of the results of the initial and second set of field measurements forthe pavement marking products for retroreflectivity, color and durability. The second set ofmeasurements was taken in July 2OO4, three months after installation of the products. It also

reports the initial measurements for retroreflectivity of the raised pavement markers (RpMs)

installed in June 2004.

il. Test Sites and Test Deck Design

I N T E RS E CT I O N M AR^KTNGS

Products for intersection ma¡kings were installed at selected intersections in the Las Vegas

Valley. The intersections are shown in Table 1 on the next page with their estimated approach

average daily traffic (ADT) for each direction. All intersections have asphalt concrete (AC)

surfaces. Four different products were installed on each intersection as stop bars and pedestrian

crossing lines, with each product installed on three different approaches of the intersection, as

shown in Figure 1.

LONGITUDINAL MARKINGS

products for longitudinal markings were installed on a section of the eastbound Desert Inn (DI)

Super-arterial, between Valley View Boulevard and Paradise Road. This section of the road had

an estimated ADT of 43,100 combined both direction in year 2003 according to the Nevada

Department of Transportation (NDOT) Annual Traffic Report. This test deck consists of two

sections, one on an asphalt concrete (AC) surface, and the other on a Portland Cement Concrete

(pCC) surface. Each product is installed on both surface types across the shoulder lane in 4-inch

wide transverse stripes (Figure 5). Each product has four lines installed on each pavement

surface.

RAISED PAVEMENT MARKERS (RPMS)

RPM test deck products were placed on Durango Drive between Satrara Avenue and Desert Inn

Road, in the City of Las Vegas. This portion of Durango Drive consists of an asphalt concrete

surface with 6 through lanes (3 in each direction), and a two-way left turn lane (TWLTL). The

avera1e annual daily traffic for this location was about 31,500 combined both directions

according to the NDOT 2003 Annual Traffic Report, Two types of markers were placed on the

test deck:

o White/red on the lane lines

¡ Yellow/yellow on the TWLTL lanes

White/red reflective RPMs were placed along skip lines at an interval of 40 feet between

markers. Yellow reflective RPMs were placed along the TWLTL lines at an interval of 40 feet

between markers. One hundred markers were placed per product. All RPMs on the test deck are

abrasion resistant.

IIL Products Installed on the Test Deck

All pavement marking products were installed on the respective test decks during the week of

April 19, 2004. RPM installation was on June t0, 2004. Vendors were responsible for

installation of their products. Some vendors performed their own installations, while other

vendors hired contractors to install their products. Traffic control was provided by Advance

Traffic Safety (ATS) and the cost was split among the participating vendors in proportion to the

number of products installed. The vendors were billed directly by ATS. All installations were

done at night to minimize impact on traff,rc. For products installed at intersections, the l2-inch

wide markings were installed side by side with the existing markings. Tables 2 and 3 summa¡ize

the products installed at the intersection sites as well as at the Desert Inn Super-arterial. Table 4

lists the products installed on the RPM test deck.

IV. Measurements of Field Performance

P AVEMENT MARKIN G MATERIAIß

In general, each installed product is supposed to provide a marking that will not flow or distort

due to temperature if the surface of the pavement remains stable. The material shall show no

fading, lifting or shrinkage, significant tearing and other signs of poor adhesion which will

significantly impair the intended use of the marking.

During the project, the installed products are evaluated based on retroreflectivity, durability, and

color. Measurements of these parameters on each product at each location are taken once every

three months for one year for intersection markings, and for two yeals for longitudinal markings

at the DI Super-arterial. For retroreflectivity and color, measurements are taken on each

pavement marking on two locations per lane, one location on the wheel path (tire track) and the

other on the skip line. For example, an intersection marking that runs across five lanes of traffic

will have measurements taken at ten different locations. Longitudinal markings at the DI Super-

arterial shall have two measurement locations per marking stripe. An average of three readings is

recorded for each measurement location. The perforrnances of the products are reported against

the cumulative number of vehicle passes computed based on 2003 ADT values.

Retrorefl ectivity measurements

Retroreflectivity measurements are taken using the LTL-2000. This instrument simulates the

light emitted from vehicle headlights 30 meters from the observation point, and measures the

amount of light that would be reflected back to the driver. The value measured is called the

coefficient of retroreflective luminance (Rl), and is measured in SI units (mcd/m2llx).

Chromacity measurements

Color measurements were taken using the BYK Gardner Color Guide. ASTM D 6628-03 and

FIIWA 23 CFR Part 655 standards were used as criteria to evaluate color properties of the

materials. Both standards use the CIE 1931 Color System. Color coordinates ("x" and "y")

represent hue on a two-dimensional coordinate system, and a luminance factor ("Y") records the

7

ligtrtness. Both standards give four coordinates (x1 through x4, yr through y4) that identify an

acceptable region, or "box", where the measured color coordinates of the products would be

serrsidered acceptable (see Figure 6, for example). Luminance readings for pavement markings

are also required to meet minimum limits, Y.¡ (see Figure 7, for example). The FTIWA standard

also specifies maximum limits, Y.u*, for certain types of markings. Table 5 shows the acceptable

color coordinate region and luminance factor limits for each standard. Both standards require that

color coordinates and luminance for a marking satisfy these limits throughout the service life of

the marking.

Table 5: Acceptable Color Coordinate Regions and Luminance Factors forEach Standard

To satisfy the color requirements for a given standard, the "x" and "y" readings for a product

must fall within the acceptance "box" while the corresponding "Y" reading has to be within the

required minimum and maximum values of the respective standards. Both the ASTM and FTIWA

standards specify a minimum acceptable value for "Y", while the FTIWA also specifies a

maximum limit. For both the "x", "y" and "Y" criteria, the FTIWA requirements are generally

more restrictive than the ASTM requirements.

Durability me asurements

Durability is a measure of how much the marking material is still left on the pavement surface in

satisfactory working condition. Durability moasurements are subjective, and shall be based on

ASTM D 913 and are reported in percentage. Two evaluators will estimate the durability of each

line and the average of the two evaluators will constitute the durability measurement for the

marking.

RETROREF LE CT N E RP M P RO D U CT S

Field measurements for retroreflectivity and durability are taken for each product at

approximately three-month intervals. For each product, measurements are taken on one of every

four markers, yielding a sampling rute of 257o.

Retrorefl ectivity measurements

Retroreflectivity measurements were taken using the ART-1200 instrument. Measwements are

taken using the 0.2 degree observation angle geometry, simulating the view of a driver of the

observation point. The standard SI unit of measure for retroreflectivity (RI) is mcd/lx'

Durability measurements

Durability is measured as a proportion of markers remaining in place and in good physical

condition. For lost markers, a distinction is made between those lost due to failure of the bonding

between the adhesive and the markers, or between the adhesive and the pavement surface.

V. Field Data and Preliminary Evaluations of Pavement Marking Materials

This section reports and summarizes observations for the field measurements for

retroreflectivity, chromacity, and durability taken approximately three months after installation

of the intersection and longitudinal products.

RET ROREF LE CT N TTY READ IN G S

Tables 6 through 16 present the retroreflectivity readings for each product and location

For intersection products, retroreflectivity readings for almost all the products have dropped

dramatically from the initial retroreflectivity readings that averaged about 370 down to about 100

for tire track locations and 140 for skip line locations (Tables 6 and 7). Products with higher

initial retroreflectivity did not necessarily end-up with higher second readings. Generally, the

three polyurea products retained a greater percentage of their initial retroreflectivity (Table 8)

compared to the tape and preformed thermoplastic products. A more detailed analysis is included

in the Preliminary Evaluations section later in this report.

With respect to the white longitudinal products installed at the DI test deck, the retroreflectivity

readings have also dropped dramatically for almost all products since installation. Many products

only retained about one half of their initial retroreflectivity readings.

Retroreflectivity readings have also dropped dramatically for almost all yellow longitudinal

products since installation. Many products only retained about one half of their initial

retroreflectivity reading. A more detailed analysis is included in the Preliminary Evaluations

section later in this report.

COLOR READINGS

Taþles 17 through 27 present the chromacity readings for each product and test location. Figures

6 tlrrough 15 show the color readings for each product plotted on against the ASTM D 6628-03

and FIIWA 23 CFR Part 655 acceptance limits. Figures 6, 8, 10, 12, and 14 present product

performance based on acceptance limits for the x and y readings. Similarly, Figures 7,9, LI, 13

and 15 present product performance based on the "Y" value.

For intersection products, the x and y chromacity readings for all products were well within the

acceptance regions under both the ASTM and FHWA standards (Figure 6 and Tables I7-I9).

However, the luminance factor "Y" readings have reduced dramatically for all intersection

products since placement and are all below the minimum specified in both ASTM and FIfWA

standa¡ds (Tables 17 - 19, Figure 7). Generally, polyurea products have retained the highest

percentage of the initial luminance, "Y.", readings.

A similar trend in chromacity readings is observed for the white longitudinal products (Figures 8,

9, L2 and 13, and Tables 20, 22, 24 and 26). Polyurea products have retained the highest

percentage of the initial luminance ("Y") readings. Also, the luminance factor "Y" for products

on the PCC test deck were generally higher than on the ACC test deck.

For the yellow longitudinal products, the chromacity readings have reduced more dramatically

than the white products from their initial values for both the x and y readings as well as the "Y"

readings. The values for the Epoplex product are significantly higher than the other pavement

markings probably because this product was placed later than the other products (see Tables 23

and 27). With respect to the x and y readings, almost all the products fell outside the more

restrictive FHWA acceptance range (Figures 10 and 14). A number of the products were also

outside the ASTM range. A complete listing of the which products were outside the acceptance

regions is presented in Table 41 in preliminary evaluations section.

DURABILTTY READINGS

Durability readings are taken by two evaluators. Each evaluator makes a subjective reading of

each marking based upon the percentage of the marking remaining in place. These percentages

a¡e then averaged for each product at each test location. Thus, the durability reading on the

placement date of every product is 100. Tables 28 through 38 present the durability readings for

each product and test location.

Durability measw€ments for intersection products have all been 95 percent or higher, with the

exception of the Brite-Line intersection tape products (Table 28). Durability measuremerÚs for

white and yellow longitudinal products on the DI test deck were all 95 percent or higher.

P R ELIMINARY EVALU ATI O N S

Retroreflectivitv

The ATM 3000 Heavy Duty and 4000 Super Duty, Ztmar HotTape 90, and Brite-Line 1500

Durable and 1600 Durable intersection products currently have tire track retroreflectivity

readings very low (Tables 6 and 7), although their corresponding skip area readings are well

above the minimum established in RTC's QPL specifications.

For white longitudinal products placed on AC, the retroreflectivity readings for Brite-Line 1500

and 1600 Durable tape and 3M Stamark 1000 polyurea products were between 100 and 20O

(Tables 9 and 11), which is below the acceptable range of values for heavy traff,rc roadways

according to the cwïent specifications in RTC's Qualified Product list. For white longitudinal

products placed on PCC, similar observations are made for Brite-Line 1500 and 1600 Durable

tape, Swarco Director 65 tape, and 3M Stamark 1000 polyurea products (Tables 13 and 15).

For yellow longitudinal products placed on AC, the retroreflectivity readings for Brite-Line 150O

Durable and 1600 Durable tapes and 3M Stamark 1000 polyurea products were between 100 and

15O (Tables 10 and 12). These products have already fallen below the acceptable minimum for

For products placed on PCC, similar observations are made for the retroreflectivity

readings for Brite-Line 1500 Durable and 1600 durable tape and 3M Stamark 1200 polyurea

products are also between 100 and 150 (Tables 14 and 16).

Chromacity

At the intersection test decks, all products have color coordinate readings "x" and "y'' within

both the ASTM and FTIWA acceptance boxes (Figure 6). However, all of these products have

"Y" readings below the ASTM and FTIWA standards (Figure 7). Table 39 shows the current pass

or fail status for these intersection products. If the reading for a particular product is marked

"Pass", then the reading is within the acceptable limit of the applicable standard. Likewise, if it is

marked "Fail", the reading is outside of the acceptable limit.

For white longitudinal products, all color coordinate readings are within both the ASTM and

FIfWA acceptance boxes (Figures 8 and 12). Few white longitudinal products are above the "Y"

minimum value for the ASTM standard (Figures 9 and 13). Ennis HPS-5 white polyurea is above

the limits for the FTIWA standard, but only on PCC.

Many yellow longitudinal products already have color cootdinate readings outside of both the

ASTM and FHWA acceptance boxes @igures 10 and 14). Yellow Products placed on PCC

generally had higher "Y" readings, and the color coordinate readings were closer to the center of

both acceptance boxes (Figures 11 and 15).

Table 40 highlights the pass or fail status of all longitudinal products placed on the Desert Inn

test deck. Readings for products marked "Skip only" indicate that the skip areas (the portion of

the marking not passing under the tire track of the lane) fall within the acceptable limit, but the

portion of the marking under the tire track does not.

The two Brite-Line intersection tape products (1500 and 1600 Durable) exhibited significant

adlresion problems (Table 28; Figure 16). All the other intersection and longitudinal products had

durability values in the 95-99 percent range displaying slight wearing, slippage, and/or tearing

(Tæbles 28-38).

V¡¡. Field Data and Preliminary Evaluations of Raised Pavement Markers

This section reports the field measurements for retroreflectivity after installation of the raised

pavement marker (RPM) Products.

RETRO REF LE CTN TTY READ IN G S

Retroreflectivity readings followed the placement of the RPM products. Two readings were

taken for each selected RPM. Thus, if 100 RPMs of one product type were placed, approximately

257o ofthese products were tested, yielding about 50 readings per product. Table 41 contains the

results of the initial retroreflectivity readings for RPM products placed on the Durango Drive test

deck.

P r eliminary ev aluatí ons

Detailed evaluations and the implications of these results with respect to the long term

performance of the products will be discussed in future reports.
