AASHTO M 320

AASHTO M 320 – Standard Specification for Performance-Graded Asphalt Binder

This specification covers asphalt binders graded by performance. Grading designations are related to the average seven-day maximum pavement design temperature and the minimum pavement design temperature. This specification contains Table 1 and Table 2. If no table is specified, the default is Table 1.
Table 2 incorporates R 49 for determining the critical low cracking temperature using a combination of T 313 and T 314 test procedures.
Note 1 – For asphalt cements graded by viscosity at 60°C, see M 226.
Note 2 – R 29 provides information for determining the performance grade of an asphalt binder.
Note 3 – For specifying performance-graded asphalt binder using Multiple Stress Creep Recovery
(MSCR), see M 332.
