Scope: 1.1 This terminology provides definitions for pavement distress for airfields, highways, roads, streets, and parking lots of all functional classifications. 1.2 This terminology covers surfaces paved with either bituminous or portland cement concrete. It does not include other paved or unpaved surfaces. 1.3 This terminology includes most of the significant types of pavement surface distresses, but it is not all inclusive. 1.4 Not all distresses noted are applicable to all pavement categories listed in 1.1. 1.5 Severity levels are not addressed in this terminology but are addressed in other ASTM test methods and practices (for example, Test Method D5340). However, a knowledge of severity levels is required for evaluating many of the distresses defined in this terminology. 1.6 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.
