About This Item

 

Full Description

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

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

1.3. Table 3 incorporates TP 70 (MSCR) for determining non-recoverable creep compliance, Jnr. For Table 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°LC, see M 226.
Note 2--R 29 provides information for determining the performance grade of an asphalt binder.
