POLYMER CONCRETE COMPOSITION FOR CEMENTITIOUS ROAD REPAIR AND OVERLAY

摘要

A composition which is useful in road overlay and repair comprises aggregate and a binder. The binder comprises a liquid epoxy resin, triethyleneglycol diamine or tetraethylene glycol diamine as curing agent, and piperazine as accelerator. The binder-aggregate system is relatively flexible, has excellent compression and flexural strength and adheres well to the substrate. Th esystem undergoes a fast cure to a compression strength of 3000 psi (210.9 kg/cm<2>) which will support automotive traffic.
