Asphalt concrete overlay is the most commonly used resurfacing technique for aged concrete pavement. However, the performance of the asphalt concrete overlay depends on how strongly the asphalt layer bond with concrete layer. Weakened bonding at the interface of asphalt and concrete pavement may contain water and deicer and eventually lead to pavement deterioration such as pothole, reflection crack, and concrete degradation. Accordingly, tensile bonding tests were conducted with various water proofing materials and the bonding performances were evaluated by using different pavement material. Emulsified asphalt waterproofing material showed superior quality in bonding, and acrylastic material waterproofing material showed inferior quality in bonding.
