PART 5 - EFFECTIVENESS OF BITUMINOUS SEALS IN PREVENTING DETERIORATION OF NEW CONCRETE BRIDGE DECKS

TWENTY-NINE NEW BRIDGE DECK SURFACES WERE USED TO TEST THE EFFECTIVENESS OF BITUMINOUS SEALS IN PREVENTING DETERIORATION OF THE CONCRETE DECKS. THESE TWENTY-NINE DECKS WERE SELECTED BECAUSE MOST OF THE DECKS HAD NOT BEEN SUBJECTED TO FREEZE-THAW CYCLES, AND NONE TO CHEMICAL DE- ICERS, PRIOR TO BEING COVERED WITH BITUMINOUS SEALS. SOME OF THE DECKS SELECTED HAD NOT BEEN EXPOSED TO TRAFFIC PRIOR TO BEING SEALED. THE RESULTS OF THIS STUDY MAY BE SUMMARIZED AS FOLLOWS: BITUMINOUS SEALS APPEAR TO BE OF VALUE FOR DECK PROTECTION AGAINST DETERIORATION OF NEW DECKS AND AGAINST TRAFFIC WEAR BY STUDDED TIRES. IT WAS FOUND, HOWEVER, THAT INITIAL SEAL PLACEMENT SHOULD BE DONE WITH CARE AND AFTER SEAL PLACEMENT REGULAR INSPECTIONS AND MAINTENANCE IS DESIRABLE. /AUTHOR/
