ASTM D913-10
(Test Method)Standard Practice for Evaluating Degree of Traffic Paint Line Wear
Standard Practice for Evaluating Degree of Traffic Paint Line Wear
SIGNIFICANCE AND USE
This practice is designed to evaluate the resistance to wear of a traffic paint. It must be remembered that a high degree of performance of paint applied to a bare road surface may not guarantee similar results when the same paint is applied over old paint lines.
SCOPE
1.1 This practice covers the evaluation of degree of resistance to wear that may occur with traffic paints (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.
