COMPARISON OF FATIGUE TEST METHODS FOR ASPHALT MATERIALS

This report describes the results of an investigation comparing various commonly used fatigue tests and evaluating the relationship between creep and fatigue. It was found that the repeated-load indirect tensile test produces results comparable with other fatigue tests if the state of stress developed in the specimen is considered. A regression analysis was conducted and an equation was developed which can be used to relate fatigue results for a variety of mixtures and test methods. A comparison of creep and fatigue results indicated that a relationship probably exists between creep and fatigue deformation and that fatigue life can possibly be estimated from creep rupture time.
