Standard Practice for Laboratory Conditioning of Asphalt Mixtures
standard by American Association of State and Highway Transportation Officials, 2022
Description
This standard practice describes procedures for laboratory conditioning of compacted and uncompacted asphalt mixtures. Two types of conditioning are described: (1) short-term mixture conditioning for volumetric mixture design and mechanical property testing (both of which simulate the precompaction phase of the construction process); and (2) long-term conditioning for mixture mechanical property testing to simulate the aging that occurs in a dense-graded surface layer over the first one to three years of a pavementʼs life. The procedures for long-term conditioning for mixture mechanical property testing are preceded by the procedure for short-term conditioning. Further information on short- and long-term conditioning is given in NCHRP Report 815.
