A polymer concrete system has been discovered which is useful in road overlay and repair. The binder for this aggregate-filled system consists of a liquid epoxy resin and triethyleneglycol diamine or tetraethylene glycol diamine curing agent. A piperazine accelerator ensures adequate strength development after short cure times at ambient temperatures. The binder-aggregate system is relatively flexible, has excellent compression and flexural strength and adheres well to the substrate. The system is distinguished by its fast cure to a compression strength of 3000 psi which will support automotive traffic.
