AASHTO R 30

Description / Abstract: This standard practice describes procedures for mixture conditioning of compacted and uncompacted hot mix asphalt (HMA). Three types of conditioning are described: (1) mixture conditioning for volumetric mixture design; (2) short-term conditioning for mixture mechanical property testing (both of which simulate the precompaction phase of the construction process); and (3) long-term conditioning for mixture mechanical property testing to simulate the aging that occurs over the service life of a pavement. The procedures for long-term conditioning for mixture mechanical property testing are preceded by the procedure for short-term conditioning for mixture mechanical property testing.

This standard practice may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
