Description

This specification covers asphalt binders graded by performance. Grading designations arerelated to the average seven-day maximum pavement design and minimum pavement designtemperatures. This specification contains Table 1, Table 2, and Table 3. If no table is specified, thedefault is Table 1.

1.2. Table 2 incorporates R 49 for determining the critical low cracking temperature using acombination of T 313 and T 314 test procedures.

1.3. Table 3 incorporates TP 70 (MSCR) for determining non-recoverable creep compliance, Jnr. ForTable 3, “S”, “H”, or “V” grade must be specified for standard, high, or very high traffic loading,respectively.

Note 1–For asphalt cements graded by viscosity at 60&degLC, see M 226.
Note 2–R 29 provides information for determining the performance grade of an asphalt binder.
