Description / Abstract:
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 Appendix X1.
