The potholes and alligator cracks in the asphalt pavement of our country's roadways have become an annoying part of our daily life. In order to reinstate and maintain our pavement infrastructure integrity and durability, we have identified dicyclopentadiene (DCPD) resin for this purpose due to its unique properties - low cost, low viscosity at beginning and ultra-toughness after curing, chemical compatibility with tar, tunable curing profile due to catalyst design. DCPD resin can penetrate into high porous pavement area to reinforce them and block water or moisture seeping channels. It also can strongly bond the pothole patches with original pavement, and hold them together for a whole. With the catalyst design, DCPD could apply for all the weather, cold or hot, wet or dry. In this paper, we will investigate the DCPD reinforcement for cold mix and hot mix for pothole repair, as well as the bonding strength improvement between repair materials and original pavement, and show that DCPD is promising materials for application in reinforced pothole patching materials.
