Abstract:Freezing and thawing tests were carried out to evaIuate the durability and compatibility of composite specimens consisting of treated concrete substrates in combination with three types of concrete overlays. The various substrate treatment/overlay combination potential candidates for bridge deck S are rehabilitation, Substrate treatment consisted of impregnating concrete with corrosion inhibitors, hydrophobic agent, pore seal ants, or a water-displacing penetrant. The overlay materials used were latex-modified concrete, low-slump dense concrete, and polymer concrete. Suitable per formance relative to both durability and compatibility was obtained only for methyl methacrylate impregnation treatment of the substrate. When used in conjunction with this treatment, all three overlays provided superior performance.*
