Asphalt Binder Aging Methods to Accurately Reflect Mixture Aging
Asphalt binders experience aging that occurs in two distinct stages under quite different conditions: (1)
short-term during construction (plant mixing, storage, placement, and compaction) and (2) long-term during
the service life of the pavement.
The TRB National Cooperative Highway Research Program's
NCHRP Research Report 967:
Asphalt Binder Aging Methods to Accurately Reflect Mixture Aging
documents research conducted
to improve laboratory binder conditioning methods to accurately simulate the short-term and long-term
aging of asphalt binders, and to calibrate the improved procedures to the aging that occur during
mixture production, transport, and placement as well as during the service life of the pavement structure.
