Asphalt Binder Aging Methods to Accurately Reflect Mixture Aging

Since aging of asphalt binder significantly influences the performance of asphalt mixtures, the specifications for performance graded (PG) asphalt binder, AASHTO M 320, Standard Specification for Performance-Graded Asphalt Binder, and AASHTO M 332, Standard Specification for Performance-Graded Asphalt Binder Using Multiple Stress Creep Recovery (MSCR) Test, include criteria for tests on residue from laboratory conditioning procedures intended to simulate the aging that occurs during construction and the service life of the pavement. The aging that occurs during construction is simulated using the short-term conditioning procedure: AASHTO T 240, Standard Method of Test for Effect of Heat and Air on a Moving Film of Asphalt Binder (Rolling Thin-Film Oven Test). The aging that occurs during the service life of the pavement is simulated using the long-term conditioning procedure: AASHTO R 28, Standard Practice for Accelerated Aging of Asphalt Binder Using a Pressurized Aging Vessel (PAV). This report documents research conducted by the National Cooperative Highway Research Program (NCHRP) to improve laboratory binder conditioning methods to accurately simulate the short-term and long term aging of asphalt binders, and (2) to calibrate the improved procedures to the aging that occurs during mixture production, transport, and placement as well as during the service life of the pavement structure.
