AASHTO M 320-22
This specification covers asphalt binders graded by performance. Grading designations are related to the LTPPBind calculated 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 AASHTO R 49 for determining the critical low cracking temperature using a combination of AASHTO T 313 and T 314 test procedures.
For asphalt cements graded by viscosity at 60°C, see AASHTO M 226.
AASHTO R 29 provides information for determining the performance grade of an asphalt binder.
For specifying performance-graded asphalt binder using Multiple Stress Creep Recovery (MSCR), see AASHTO M 332.
