The application of polymer modified concrete and quick-settig cement in bridge deck patching can drastically reduce the downtime experienced with conventional PCC (portland cement concrete) patching, thus avoiding extended traffic snarls and bridge closings. Points to be considered before a bridge deck is actually patched are listed. Inspection of the deck using nondestructive methods is described, as well as deck removal, and patching procedures. Polymer-modified concrete, resin-based mortars, epoxies and quick-set cements have been developed that allow traffic to be placed on patched pavements in as little as 10 minutes to 2 hours. The four procedures that comprise patching are described and include surface preparation, repairs, resurfacing, and sealing. Details of the placing of the material are also described.
