Abstract
A polymer concrete system has been discovered which is useful in road overlay and repair in both wet and dry conditions. The binder for this aggregate-filled system consists of a liquid epoxy resin and triethyleneglycol diamine or tetraethylene glycol diamine combined with polyoxypropylene glycol diamine curing agent. A piperazine accelerator ensures adequate strength development after short cure times at ambient temperatures. The binder-aggregate system is relative flexible, has excellent compression and flexural strength and adheres well to the substrate. The system is distinguished by its binding strength to smooth or rough surfaces whether the surfaces are wet or dry.
