AASHTO M 320: Standard Specification for Performance-Graded Asphalt Binder
DOD Adopted ANSI Approved Approved
This specification covers asphalt binders graded by performance. Grading designations are related to the average seven-day maximum pavement design and minimum pavement design temperatures.
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 MP 19.
