scope:

This specification covers asphalt binders graded by performance using the multiple stress creep recovery (MSCR) test. Grading designations are related to the average seven-day maximum pavement design temperature, minimum pavement design temperature, and traffic loading.

This specification incorporates T 350 for determining non-recoverable creep compliance, J_nr. "S," "H," "V," or "E" designations must be specified for standard, heavy, very heavy, or extremely heavy traffic loading, respectively.

Note 1-For asphalt cements graded by viscosity at 60°C, see M 226.

Note 2-For performance-graded asphalt binder, see M 320.

To ensure that the asphalt binder exhibits elastic response, the specifying agency may require compliance with R 92.
