AASHTO M 332-21 PDF Download

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, Jnr. "S," "H," "V," or "E" designations 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.
To ensure that the asphalt binder exhibits elastic response, the specifying agency may require compliance with R 92.
