AASHTO M 332:2018 Standard Specification for Performance-Graded Asphalt Binder Using Multiple Stress Creep Recovery (MSCR) Test

AASHTO M 332:2018 Standard Specification for Performance-Graded Asphalt Binder Using Multiple Stress Creep Recovery (MSCR) Test. 3. TERMINOLOGY 3.1. Definitions: 3.1.1. Definitions for many terms common to asphalt binder are found in ASTM D8. 3.1.2. asphalt binder—an asphalt-based cement that is produced from petroleum residue either with or without the addition of nonparticulate organic modifiers. 4. ORDERING INFORMATION 4.1. When ordering under this specification, include in the purchase order the performance grade (PG) of asphalt binder required including the designation for traffic loading (e.g., M 332, PG 64V-22). 4.1.1. If required to comply with the elastic response requirements in R 92, include reference to R 92 in the purchase order (e.g., M 332, PG 64V-22. R 92, Percent Recovery of X). 4.2. The required environmental asphalt binder grades may be selected by following the procedures described in M 323 and R 35, except do not use the “grade bumping” procedure in M 323. Select bb the environmentally appropriate high- and low-temperature grades and the appropriate S. H, or “Ii” grade for the expected traffic level and traffic load rate. 4.2.1. Standard Designation “S” in most typical situations will be for traffic levels fewer than 10 million Equivalent Single Axle Loads (ESALs) and more than the standard traffic speed (>70 km/h). 4.2.2. High Designation “H” in most situations will be for traffic levels of 10 to 30 million ESALs or slow-moving traffic (20 to 70 km/h). 4.2.3. Very High Designation “V” in most situations will be for traffic levels of greater than 30 million ESALs or standing traffic (
