1. Scope

1.1 This specification covers asphalt binders graded by performance. Grading designations are related to the average seven-day maximum pavement design temperature, and minimum pavement design temperature. This specification contains and . incorporates Practice D 6816 for determining the critical low cracking temperature using a combination of Test Method D 6648 and Test Method D 6723 test procedures. If no table is specified, the default is .

For asphalt cements graded by penetration at 25C, see Specification D 946. For asphalt cements graded by viscosity at 60C see Specification D 3381.

AASHTO R 29 provides non-mandatory information for determining the performance grade of an asphalt binder.
