AASHTO R 30

Abstract

This practice describes procedures for mixture conditioning of compacted and uncompacted hotmix 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 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 long-term conditioning for mixture mechanical property testing procedures are preceded by the procedure for short-term conditioning for mixture mechanical property testing.<br><em>This standard 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.</em>
