Title: EXAMPLES OF REPAIRS TO CONCRETE IN BRIDGES
Accession Number: 00218295
Record Type: Component
Abstract: THE WORK OF THE THE HIGHWAY DISTRICTS IN NEW YORK THAT SUPERVISE ALL CONSTRUCTION WORK AND DO THE MAINTENANCE WORK ON ALL HIGHWAYS AND BRIDGES BELONGING TO THE STATE SYSTEM IS DESCRIBED. THE MAINTENANCE CREWS ARE EQUIPPED TO DO ORDINARY MAINTENANCE WORK AND SNOW REMOVAL BUT ARE NOT EQUIPPED TO DO MAJOR STRUCTURAL REPAIR WORK. SUCH WORK IS DONE BY CONTRACT, USING CONSTRUCTION RATHER THAN MAINTENANCE MONEY. DETERIORATION OF SURFACE COURSES ON BRIDGE DECKS IS PREVALENT. THE DETERIORATED WEARING COURSES ARE CONCRETE SLABS OR ASPHALT WEARING COURSES. THE COST OF REHABILITATING SOME OF THE OLDER BRIDGES OFTEN EXCEEDS THE ORIGINAL COST OF THE BRIDGE BUT TRAFFIC CAN USUALLY BE MAINTAINED WHILE REPAIRING THE BRIDGE AND STILL AT ONLY ABOUT ONE-FIFTH THE COST OF A NEW BRIDGE. ABOUT FIVE YEARS AGO, NEW YORK STATE BUREAU OF BRIDGES STARTED USING AIR-ENTRAINMENT IN STRUCTURAL CONCRETE. THERE ARE NO EXAMPLES OF REPAIR TO AIR- ENTRAINED CONCRETE YET. ORIGINAL CONSTRUCTION AND REPAIR OF THE FOLLOWING BRIDGES ARE DESCRIBED: GLENS FALLS BRIDGE, WATERFORD BRIDGE AND WESTERN GATEWAY BRIDGE.
