SELECTION AND EVALUATION OF METHODS AND TREATMENTS FOR ACCEPTABLE FATIGUE LIFE OF MOISTURE-SUSCEPTIBLE DENSE-GRADED ASPHALT CONCRETE

The objective of the study was to evaluate four aggregate sources in southern Idaho from the basis of moisture damage susceptibility when the aggregate is incorporated into dense-graded asphalt concrete mixes. Field cores and performance information from four representative pavements were used with the laboratory test information obtained from laboratory specimens. Laboratory mechanical indicator tests that were used to reflect the moisture damage susceptibility were: splitting tensile strength, resilient modulus and repeated stress diametral fatigue. These tests were performed on dry, vacuum saturated and accelerated conditioned laboratory specimens and cores. Three of the four aggregate source mixes were evaluated both in untreated and treated conditions. Pavement lives were predicted by two calculation methods using both the splitting tensile strength ratios and the fatigue lines. (Author)
