SIMPLE PROCEDURE FOR FATIGUE CHARACTERIZATION OF BITUMINOUS CONCRETE
The objective of this project was to develop a simple test to design bituminous concrete mixtures for fatigue resistance. Included are two literature reviews: (1) current fatigue testing procedures, and (2) simple test methods that offer possibilities for fatigue prediction. Seven bituminous concretes representing five areas of the United States were tested by a beam fatigue apparatus and several selected simple test methods. Correlations were performed between fatigue results and simple test results, and the best correlations were obtained with the indirect tensile test. Indirect tensile test results correlate with the stress-fatigue life curve under the constant stress fatigue test mode and the strain-fatigue life curve under the constant strain fatigue test mode. The main conclusion is that the indirect tensile test can be used to predict the fatigue characteristics of bituminous concretes and a simple test method is recommended.
