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 D 5340). However, a knowledge of severity levels is required for evaluating many of the distresses defined in this terminology.
