A LABORATORY TEST SYSTEM FOR PREDICTION OF ASPHALT CONCRETE MOISTURE DAMAGE

Representative results are described and shown for a practical laboratory test system developed to predict moisture damage in asphalt concrete pavements or to monitor the rate of moisture damage in existing pavements. Moisture-damage predictions are based on the results of tensile strength and tensile E-moduli tests performed on laboratory-fabricated specimens that have undergone freeze-soak and thermal-cycle accelerated moisture conditionings. These test results are compared to similar mechanical tests on pavement cores. The conventional laboratory specimens were made to duplicate pavements that were sampled throughout the United States and that had various levels of moisture damage. Implications of using the test system for predictability of moisture damage are discussed.
