12937887PDFTech ReportVHTRC 83-R28VirginiaVirginia Transportation Research CouncilSprinkel, Michael MVirginia Highway & Transportation Research CouncilUS Transportation CollectionThe installation of a thin polymer concrete overlay on the Beulah Road bridge demonstrates that an overlay of low permeability and high skid resistance can be successfully installed by maintenance forces with a minimum of disruption to traffic, approximately 8 hr. per lane, and at about half the cost of alternative service-life-extending measures. Subsequent laboratory tests have indicated that thermal stress at the bond interface can cause the formation of cracks in the overlay, the bond interface or the base concrete. The problem could be minimized by the application of a more flexible PC overlay
