Evaluation of concrete bridge deck overlays
… been used by many states for the protection of bridge decks, but the premature delaminations and failures have been observed in many cases. A comprehensive study was recently defined to investigate overlay performance in collaboration with the West Virginia Department of Transportation-Division …

Design and performance of cost-effective ultra high performance concrete for bridge deck overlays
… performance concrete (UHPC) for bonded bridge deck overlays. The high durability and mechanical properties of such repair material can offer shorter traffic closures and prolong the service life of the pavement. The UHPC was optimized using supplementary cementitious materials (SCMs), …

Shrinkage of Latex-Modified and Microsilica Concrete Overlay Mixtures
Highway bridge decks are often overlaid to extend service life by reducing the rate of chloride ion ingress and the rate of corrosion of reinforcing steel in the sound chloride-contaminated concrete that is left in-place. Bridge deck overlays in Virginia are usually either latex-modified concrete …

NEW GENERATION POLYMER CONCRETE INCORPORATING CARBON NANOTUBES
… fine and coarse aggregate in the mixes, while PC overlays incorporated fine aggregate only. Test protocols included investigating the mechanical properties of PC, examining the bond strength of the PC overlays with steel and microstructural characterization of epoxy-MWCNTs nanocomposite. iv …
