The Vermont Agency of Transportation recently evaluated the performance of a high-friction bridge deck overlay system that also functions as a waterproofing membrane. The quick-curing overlay consists of an aggregate chip seal affixed with a synthetic polymer epoxy. Five years after application on a low-volume bridge, annual site visits and structures inspections have shown the bridge and overlay to be in good condition, and the system has provided good skid resistance and waterproofing.
