Description

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 TP 70 for determining non-recoverable creep compliance, J_nr. “S”, “H”, “V”, or “E” grades must be specified for standard, high, very high, or extremely high 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.
