Scope of standard 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. |
