Abstract:
Rapid abrasion of asphaltic concrete and Portland cement concrete pavements due to studded tires and tire chains in snowy and cold regions in Japan has been a serious problem from the viewpoint of environmental and health conditions. To solve the above abrasion problem, resin mortar, composed of methyl methacrylate (MMA) resin and hard aggregate, was applied in an overlay on existing pavements. In addition to its physical properties, abrasion of MMA resin mortar and concretes was first investigated in laboratory test. The remarkable characteristics of MMA resin mortar are its high early strength, curing even in low temperature, and high abrasion resistance. Subsequently, an overlay of MMA resin mortar was constructed on the pavement of the toll road gate. Abrasion depth has been measured for 7 years under traffic loads since 1988. From the results, the performance of MMA resin mortar was compared with that of asphaltic concrete and Portland cement concrete.
