scope:

This specification covers asphalt binders graded by performance using the multiple stress creep recovery (MSCR) test. Grading designations are related to the LTPPBind calculated 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.
