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 Southern Nevada. Three types of products are evaluated based on their intended usage:

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

presents details of the test deck results through the sixth set of field measurements for

retroreflectivity, color, and durability taken in October 2005 on the longitudinal products. The

fourth set of field measurements for RPM products that were also to be taken in October 2005

were not done due to faulty equipment. The equipment, ART-1200, had to be shipped back to the

vendor for repairs. It is expected that the equipment will be available for the January 2006

measurements. Products for longitudinal markings were 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 distott

due to temperature if the surface of the pavement remains stable. The longitudinal products are

evaluated based on retroreflectivity, durability, and color (chromacity). Measurements of these

parameters on each product at each location are taken once every three months for two years.

Similarly, field measurements for retroreflectivity and durability for RPMs are taken at intervals

of three months for two years.

As reported previously, retroreflectivity and chromacity readings have dropped

significantly for all longitudinal products since installation. Some of these products have fallen

below RTC's current QPL specifications. Durability measurements for the longitudinal products

are almost all close to 95 percent or higher. Regarding RPM durability, some markers have lost

the reflective glass surfaces entirely. Also, a small amount of markers have broken glass surfaces

or broken as of the July 2005 measurement.

I. 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

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

(RTC) of Southern Nevada. This list is used by the various local transportation 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 reporl presents details of the results of the initial through the sixth set of field

measurements for the pavement marking products for retroreflectivity, color and durability. The

sixth set of measurements was taken in October 2005, approximately fifteen months after

installation of the products. However, the equipment for retroreflectivity measurements of

RPMs, the ART 1200, was broken down at the time of taking measurements and had to be

shipped back to the vendor for repairs. It is anticipated to be back in time for the January

readings. As such, the latest readings available and presented in this report for the RPMs are the

July 2005 readings.

il. Test Sites and Test Deck Design

INTERSECTION MARKINGS

Products for intersection markings \¡/ere installed at selected intersections in the Las Vegas

Valley. The intersections are shown in Table I 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 l.

LONGITUDINAL MARKINGS

Products for longitudinal markings Ìvere 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 directions in year 2003 (source: Nevada Department

of Transportation (NDOT) Annual Traffic Report 2003). 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

transvorse 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 Sahara 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

average annual daily traffic for this location was about 31,500 combined both directions (source:

Nevada Department of Transportation (NDOT) Annual Traffic Report 2003), Two types of

markers were placed on the test deck:

o White/red on the lane lines

o Yellow/yellow on the T'WLTL 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.

J

ilI. 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 completed on June 10, 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 traffic. For products installed at intersections, the l2-inch

wide markings were installed side by side with the existing markings. Tables 2 and 3 summarize

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 MATERIALS

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 years 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 performances of the products are

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

Retrorefl ecti vity 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/m'llx¡.

Chromacitv 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

lightness. Both standards give four coordinates (x¡ through x+, yt through y+) that identify an

1

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

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

are also required to meet minimum limits, Yn¡n (see Figure J , 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 servìce life of

the marking.

X1Standard/Color Yrnu*Y-i.Y+X4YtX3YzXZYt

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 FFIWA

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

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

more restrictive than ths ASTM requirements.

Durability measurements

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

satisfactory working condition at the time of data collection. Durability measurements are

subjective, and shall be based on ASTM D 913 and are reported in percentage. Two evaluators

estimate the durability of each line and the ayerage of these two readings constitute the durability

measurement for the marking.

RETROREFLECTNE RP M PROD U CTS

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, for a sampling raþ of 25Vo.

Retr-orefl ecti vity measurç¡qe.nts

Refforeflectivity measuremerits were taken using the ART-1200 instrument. Measurements are

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

observation point. The standæd SI unit of measure for reüoreflectivity (RI) is mcd/lx.

Durability measurements

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

condition. Forlost markers, a distilction 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 fifteen months after installation

of the longitudinal products. Field measurements for intersection products were completed in

April 2005 and the final values, evaluations and recommendations for these products have

already been presented to the RTC. These products are not discussed in this report.

RETRO REF LE CTIV ITY READ IN G S

Tables 6 through 13 present the retroreflectivity readings for each longitudinal product and type

of surface. The results show a wide range of performance, from retroreflectivity values in the

low 30's to the high of 400. Once again, some readings are higher than the readings for the

previous period due to the fact that these latest readings were taken about a week after a

rainstorm. Overall, as expected, white products performed better than yellow products. Between

the AC and PCC surfaces, the overall performance was relative similar. Howevet, polyrrea

products generally performed better on the PCC surface than on the AC surface. A more detailed

analysis by products is included in the Preliminary Evaluations section later in this report.

COLOR READINGS

Tables 14 through 21 present the chromacity readings for each product and test location. Figures

6 through 13 show the color readings for each product plotted on against the ASTM D 6628-03

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

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

13 present product performance based on the "Y" value.

For white longitudinal products, the x and y chromacity readings for all products were well

within the acceptance regions under both the ASTM and FFfWA standards (Figures 6 and 8).

However, the luminance factor "Y" readings have reduced significantly for all longitudinal

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

standards (Figures '7 and 9). Tape products have retained the highest percentage of the initial

luminance ("Y") readings. Also, the luminance factor "Y" for products on the AC test deck were

generally higher than on the PCC test deck.

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

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

readings. With respect to the x and y readings, all but one of the products fell outside of both the

FFIWA and ASTM acceptance ranges (Figures 8 and 12). A complete listing of the status of each

product with respect to the chromacity thresholds is presented in Table 30 in the Preliminary

Evaluations section.

DURABILITY READINGS

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

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

are then averaged for eaeh product at Bach testlocation. Thus, the durability of a product at the

time of installation is 100. Tables 22 throttgh 29 present the durability readings for each product

and test location. All but one longitudinal products had durabilitl' values of at least 95Vo. The

lone procluct with durability in the uppor 80's and lorver 90's was the po-lyurea product Epoplex.

The RTC's QPL standards require that durability rernain at or above 98Vo fw white longitudinal

products used on heavy volume roadways, and 957a for yellow longitudinal products on heavy

volume roadways.

P RELIM IN ARY EVALU AT I O N S

Retroreflectivity

The white longitudinal products that have performed relatively well so far, with avenage tire/skip

retroreflectivity readings of over 180 on both the AC as well as the PCC surfaces, include 3M

Stamark 380IES, ATM 3000, Ennis IIPS-5, Epoplex LS90, Swarco Director 60 and Swarco

Director 90. On the other hand, performing poorly with values under 100 are Briteline 1500

Durable and Briteline 1600 Durable.

For yellow products, the following products performed well with average retoreflectivity

readings of at least 180, namely, 3M Stamark 380IES, Ennis F{PS-5, Epoplex LS90, ATM 4000

(on PCC), and Swarco Director 35 (on AC). Poorly performing products on both surfaces include

Briteline 1600 Durable, 3M Stamark 1000, and 3M Stamark 1200

Chromacity

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

FHWA acceptance boxes (Figures 6 and 10). However, none of the white longitudinal products

are above the "Y" minimum value for the ASTM or FFfWA standards (Figures 7 and l1).

For the yellow products, almost all products had the x and y color-coordinates outside of both the

FIIWA and ASTM acceptance boundaries or box (Figures 8 and 12) on both the PCC and AC

surfaces. Also, the chromacity "Y" readings are generally below both the FFIWA and ASTM

minimum thresholds except for a couple on products (Figures 9 and 13).

Table 30 presents the pass/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. Some products are also marked "Tire only",

indicating that the tire tracks were acceptable, whereas the skip areas were not.

JI

Table 30: ASTM and FIfWA Chromacity Pass or Fail for Longitudinal Products

Durabilit)¡

Almost all the longitudinal products had durability values essentially the same relative to the

previous readings, at close to 95Vo and above (Tables 22-29) with no significant wearing,

slippage, and/or tearing. Only Epoplex LS90 had lower durability values of about 887o and 9l7o

on the AC and PCC surfaces, respectively.

VI. Field Data and Preliminary Evaluations of Raised Pavement Markers

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

pavement marker (RPM) products.

RETRO RE F LE CTIV ITY READ I N G S

Table 3l below presents a summary of the letroreflectivity readings for the different

measurement periods since installation in June 2004 ap to July 2005. Although all products have

dramatically reduced retroreflectivity values, the Apex 9214R appears to be outperforming the

other two products for both the white/red and yellow/yellow products.

DURABILITY READINGS

For durability, every installed RPM was inspected and evaluated on its presence, physical

condition and placement. Missing markers with and without glue backings, broken markets,

markers that slid out of place, and markers with broken glass were recorded. The number of

markers remaining in good condition were then summed and compared to the original amount of

markers placed. Table 32 shows the durability evaluation results through the most recent

observation period, July 2005. It appears that with over 93Vo of the markers still in good

condition, all products are performing well except the yellow/yellow Swareflex Vita-Lite, which

appear to be losing their the reflective glass surfaces entirely. The Apex 921 AR has a few

markers having broken glass surfaces.
