PART 9 EPOXY RESIN SEAL COATS AND EPOXY MORTAR PATCHING FOR BRIDGE DECKS

SEVERAL PROBLEMS AND APPROACHES ARE DISCUSSED RELATING TO USING EPOXY RESIN FOR BRIDGE DECK SEALS AND FOR MORTAR PATCHING MATERIAL FOR REPAIRING POTHOLES IN KANSAS BRIDGE DECKS. IN SPITE OF IMPROVEMENTS IN EPOXY APPLICATION RATES AND SEALING PRACTICES, THE BRIDGE DECKS UNDER EPOXY "SEALS" HAVE CONTINUED TO EXHIBIT SPALL AND HOLLOW PLANE TYPE OF DETERIORATION. EPOXY MORTAR PATCHING MATERIAL WITH LESS THAN ONE PERCENT ABSORPTION WAS OBTAINED BY MIXING ONE PART EPOXY, ONE PART PORTLAND CEMENT AND FIVE PARTS OR LESS OF FINE SAND. THIS MIX MAKES A GOOD PATCHING MORTAR BUT ALL UNSOUND CONCRETE MUST BE FIRST REMOVED FROM THE POTHOLE IF THE REPAIR IS TO BE SUCCESSFUL. /AUTHOR/
