FACTORS AFFECTING MOISTURE SUSCEPTIBILITY OF ASPHALT CONCRETE MIXES (WITH DISCUSSION)

Factors affecting the moisture susceptibility of asphalt-aggregate mixes were examined using the freeze-thaw pedestal test and resilient modulus and indirect tensile testing of water-conditioned laboratory-made cores. Major factors affecting performance in the pedestal test include aggregate type, void content, lime addition, mixing temperature, and hot-mix storage time.
