ASTM D913-20

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D913 − 15 D913 − 20
Standard Practice for
Evaluating Degree of TrafficPavement Marking Line Wear
This standard is issued under the fixed designation D913; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice covers the evaluation of degree of resistance to wear that may occur with trafficpavement 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,concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and
determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 failure, described by these photographic references, n—that condition manifested in trafficpavement markings by actual
detachment of sections of the film from its substrate or erosion of sections of the marking down to the substrate.
3.1.1.1 Discussion—
The degree of resistance to failure is judged by the amountarea of substrate that is covered.covered by the pavement marking.
3.1.2 substrate, n—the roadway surface or previously applied traffic marking over which the trafficpavement marking being
tested was applied.
4. Significance and Use
4.1 This practice is designed to evaluate the resistance to wear of a trafficpavement marking. It mustshould be rememberednoted
that a high degree of performance wear resistance of trafficpavement marking applied to a bare roadpavement surface may not
guarantee similar results when the same trafficpavement marking is applied over old markings.
5. Type of Failure
5.1 The failure as described in Section 3 does not presume any specific mechanism, and all areas where the substrate is visible
shall be considered a failure.
This practice is under the jurisdiction of ASTM Committee D01 on Paint and Related Coatings, Materials, and Applications and is the direct responsibility of
Subcommittee D01.44 on Traffic Coatings.
