• Abstract:
  A major study of asphalt concrete properties and performance of Alaska's highways was completed in 1982. The project data base was obtained from 117 statewide pavement sections through numerous core samples and measurements of cracking, patching and rutting. Primary research objectives were to: 1) provide an idea of the in-service composition of asphalt concrete, and 2) determine composition variations which produce the best performance. Because of the apparent rapidity of asphalt age hardening, performance relationships were derived using aged properties. Results indicate that best long-term performance is obtained from asphaltic materials which retain softness and relatively low tensile strengths throughout the pavement's service life. Aged materials specifications are presented which have provided optimum performance.
