Book excerpt: The reported research examines the bond strength between overlays placed over bridge decks which are sealed with epoxy resin or high molecular weight methacrylate (HMWM) sealers. The study involved field and laboratory experimental testing of cores under direct shear, Strategic Highway Research Program (SHRP) interfacial specimens, beams, and a 1/3-scale bridge subassembly of a typical steel stringer bridge. Micro-silica modified concrete, latex modified concrete, and superplasticized dense concrete overlays were used in this study. The experimental data were complemented with finite element studies. Despite often stark variations in the values of bond strength obtained from different testing methods, the data universally suggest that the use of a sealer at the interface can reduce the available bond strength.
