SIMPLE TEST PROCEDURE FOR PREDICTING FATIGUE LIFE OF BITUMINOUS CONCRETE
An examination of several simple test methods revealed that the indirect tensile test can be used to predict the fatigue life of bituminous concrete in place of the traditional expensive and time-consuming flexural fatigue test. The simple tests examined -- indirect tensile, double punch, resilient modulus, flexure, resonant frequency, and pulse velocity -- were selected through a literature search and were used to test several mixes. The mixes were obtained from various locations in the United States and contained a variety of asphalt cements and aggregates. The traditional flexural fatigue test was also performed on each mix and the results were correlated with those from the simple tests. The correlations indicated that indirect tensile strength and stiffness can be used to predict the fatigue behavior of bituminous concrete. The indirect tensile test method can be used to design mixes for an adequate fatigue service life.
