ASTM D6628-03

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.
