TEST 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. This replaces the traditional, expensive, and time-consuming flexural fatigue test. The tests examined--indirect tensile, double punch, resilient modulus, flexure, resonant frequency, and pulse velocity--were selected from a literature search for use on several mixes obtained from variaous locations in the United States and containing 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 method can be used for designing mixes with adequate fatigue service lives. /Author/
