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.
