The final report summarizes the results of a study of the use of epoxy compounds in the shallow surface repair and sealing of concrete bridge decks. The research effort concentrated on the use of epoxy resin systems as bonded overlays and included evaluations of test strips of seven materials on two structures in Northern Virginia, supplemented by observations of approximately fifty full-scale applications. The wearing of a thin bonded epoxy overlay exposed to traffic, as manifested in the loss of both skid resistance and protection afforded the underlying concrete, is the definitive factor in the service life of the application. The resistance to wearing of the exposed overlays observed in this study was generally disappointing and the use of an asphaltic wearing course to protect the epoxy seal coat was considered essential.
