The construction, performance and use of polymer concrete bridge overlays over the past 25 years is summarized. Polymer concrete overlays that have an established history of use and acceptance include multiple-layer epoxy, multiple-layer epoxy urethane, methacrylate slurry and premixed polyester styrene. Evaluations indicate that polymer concrete overlays can provide skid resistance and protection against intrusion by chloride ions for 25 years and are an economical technique for extending the life of concrete decks, particularly when overlays must be constructed during off-peak traffic penods to minimize inconvenience to motorists.
