Standard Method of Test for
Short-
and Long-Term Aging of Bituminous Mixes
SHRP Designation: M-0071
1. SCOPE
1.1 This method describes the short- and long-term aging procedures for compacted
and uncompacted bituminous mixtures. Two types of aging are described: 1) short-term aging
of uncompacted mixtures to simulate the precompaction phase of the construction phase, and
2) long-term aging of compacted mixtures to simulate the aging that occurs over the service
life of a pavement. The long-term aging procedures should be preceded by the short-term
aging procedure. Evaluation of the extent of aging should be performed using a resilient
modulus test (ASTM D 4123-82), dynamic modulus test (ASTM D 3497-79) or other
approved test.
1.2 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.
1.3 The values stated in SI units are to be regarded as the standard. The values in
parentheses are for information only.
