Moisture damage is one of the common distresses found in asphalt pavements. Polymer additives to asphalt not only decrease temperature susceptibility, but can also improve adhesion and cohesion and resistance to moisture-induced damage. Ethylene propylene diene monomer (EPDM) is a polymer waste and is found abundantly in Louisiana. Earlier studies have shown that chemically treated EPDM could be used as a viable modifier in asphalt cement and when incorporated in asphalt concrete mixes showed enhanced stiffness and creep properties. The objective of this study was to examine the moisture susceptibility behavior of conventional and EPDM modified asphalt concrete mixes. A dense graded mix incorporating three-control asphalt cements and two EPDM modified asphalt cements were studied. The results of the study show that the EPDM modified asphalt concrete mixes are prone to moisture damage and the use of an antistripping additive is very effective. |
