Asphalt Mixture Behavior in Repeated Flexure: A Study of an In-Service Pavement Near Morro Bay, California

摘要

The report is part of a continuing study of the fatigue response of asphalt paving mixtures which includes not only the behavior of mixtures in repeated flexure but also consideration of the fatigue factor in the design of A. C. pavements. For this project, investigations have included: (1) laboratory fatigue tests both on specimens sawed from the asphalt concrete course and on laboratory-prepared specimens with the same components; (2) triaxial compression repeated load tests on the other components of the pavement section as well as the subgrade material; and (3) prediction of the potential for fatigue distress in this pavement section.
