Evaluating the Effect of Different Moisture Conditioning Protocols on Asphalt Concrete Moisture Damage Resistance

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Several laboratory test protocols exist as standards for evaluation of moisture damage resistance of compacted asphalt concrete mixtures: indirect tensile strength after freeze-thaw conditioning, performance evaluation when submerged under water and subjected to repeated wheel tracking, and measuring the strength or modulus after conditioning of the mixture when subjected to moisture induced stress test (MIST). This study was undertaken to compare the conditioning effect from a freeze-thaw cycle, hot-water bath conditioning (no freeze), and the MIST conditioning. The dynamic modulus and indirect tensile strength of these asphalt mixtures were determined before and after conditioning. It was found that the tensile strength ratio (TSR) for the mixtures exposed to only the hot water bath was significantly lower than those subjected to the freeze-thaw cycle. Drop of mix modulus was observed as a result of moisture-induced damage, albeit to various degrees. Slightly a higher drop of modulus was observed from the freeze-thaw conditioning compared with the MIST conditioning for three of the mixtures.
