ASTM D6628-03(2015)
(Specification)Standard Specification for Color of Pavement Marking Materials
Standard Specification for Color of Pavement Marking Materials
ABSTRACT
This specification covers the daytime and nighttime color of retroreflective pavement marking materials, both painted and tape lines, including thermoplastic, epoxy and other types, used for traffic control lane markings and symbols on road surfaces. This specification is not applicable to the testing, for quality control purposes, of marking material without added drop-on beads. The performance requirements for which the marking materials shall be tested on and conform accordingly to are the daytime and nighttime chromaticity limits, retroreflectance, and daytime lightness limits (Y tristimulus coordinate).
SCOPE
1.1 This specification covers the daytime and nighttime color of retroreflective pavement marking materials used for traffic control lane markings and symbols on road surfaces. It is intended to apply throughout the service life of the material.
1.2 This specification applies to both painted and tape lines, including thermoplastic, epoxy and other types.
1.3 This specification is not applicable to the testing, for quality control purposes, of marking material without added drop-on beads.
1.4 In addition, it does not describe requirements other than color such as retroreflectance.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5.1 Exception—This specification is noted to be a SI document, where angles are generally expressed in radians. However, as angles used in retroreflection have historically been identified in degrees, the International Committee for Weights and Measures (CIPM, Comité International des Poids et Mesures) accepts the use of degrees with SI units, and European Normatives and documents from the International Commission on Illumination (CIE) use degrees for retroreflection geometry.

4. Significance and Use
4.1 This specification is intended for use during the lifetime of the retroreflective pavement marking on the road surface.
Specifications for characteristics other than color are found in other ASTM documents.
5. Performance Requirements
5.1 Chromaticity Limits—The material must plot within the boundaries described by the four corner points listed in Tables 1
and 2 when measured in accordance with the test methods in Section 7.
5.1.1 Table 1—Daytime (x,y) chromaticity coordinates of the corners of the regions for the colors of white, yellow, blue and
red pavement markings.
5.1.2 Table 2—Nighttime (x,y) chromaticity coordinates of the corners of the regions for the colors of white and yellow
pavement markings.
5.1.3 Chromaticity and Retroreflectance—The third dimension of the perceived appearance of the road marking at night is the
retroreflectance. This quantity is specified in other ASTM documents on pavement markings and is not part of pavement marking
nighttime color specification. Research has shown that the nighttime color as specified by chromaticity is sufficient and adequate
for the color naming of the material as viewed under nighttime conditions.
