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.

Note 1-For asphalt cements graded by penetration at 25°C, see Specification D 946. For asphalt cements graded by viscosity at 60°C see Specification D 3381.

Note 2-Proposed Practice P 249 provides non-mandatory information for determining the performance grade of an asphalt binder.
