CREEP EFFECTS ON FATIGUE TESTING OF ASPHALT CONCRETE

An effort has been made to present a different approach to the analysis of elastic, fatigue, and fracture properties of asphalt concretes. It has been suggested that asphalt viscosity, asphalt content and complex flow, and the compacted density of the mix influence both the elastic properties and extensibility of the asphalt mix which in turn governs fatigue life. The application of a creep model to predict fatigue failure which is a result of cumulative plastic deformation has been explored. The results indicate that the creep model needs to be revised to incorporate effects of density and/or binder content.
