ASTM D913-15

4.1 This practice is designed to evaluate the resistance to wear of a traffic marking. It must be remembered that a high degree of performance of traffic marking applied to a bare road surface may not guarantee similar results when the same traffic marking is applied over old markings.

1.1 This practice covers the evaluation of degree of resistance to wear that may occur with traffic markings in road tests (see Practice D713) or in actual service, using photographic standards for comparative evaluation.

1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
