AASHTO M 332-19

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 AASHTO 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.

For asphalt cements graded by viscosity at 60°C, see AASHTO M 226.

For performance-graded asphalt binder, see AASHTO M 320.

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

This standard was formerly designated as provisional standard MP 19.
