EVALUATION OF MEMBRANE WATERPROFFING

IN ORDER TO GATHER PERTINENT INFORMATION ON THE LABORATORY TESTING AND EVALUATION OF STANDARD GLASS FABRIC AND ASPHALT MEMBRANE SYSTEM AND TO DETERMINE IF NEWER TYPES OF MEMBRANE SYSTEMS WOULD BE WORTHY OF FIELD TRIAL AS A POSSIBLE REPLACEMENT OF THE PRESENT SYSTEM OF PREVENTING WATER FILTRATION THROUGH BITUMINOUS PAVEMENT FROM REACHING THE BRIDGE DECK SLAB, LABORATORY TESTS WERE MADE ON TWELVE MEMBRANE SYSTEMS INCLUDING STANDARD ASPHALT AND GLASS FABRIC. THE TYPES WHICH COULD BE CATEGORIZED INTO REINFORCED (TYPE B ASPHALT AND 2-LAYER GLASS FABRIC; PROTECTO WRAP; BITUTHENE; NORDEL-TYPAR) AND NON-REINFORCED (UNIROYAL 6125; WITMER 520; EDCO U-FLEX UNDERLAY; POLYLOK 165; FRED A. WILSON CARBOLASTOMERIC; ANTI-HYDRO SEAMLESS DECK MEMBRANE; KEEPER KOTE N1-1) WERE EVALUATED AFTER SUBJECTION FIRST TO A TEMPERATURE OF MINUS 25 DEGREES F AND THEN TO HEAT. ON PASSING BOTH PHASES OF THESE TESTS, THE MATERIAL IS RECOMMENDED FOR FIELD STUDY UNDER AN EXPERIMENTAL BASIS. UNIROYAL, ALTHOUGH NON-REINFORCED, DOES EMPLOY A FLEXIBLE RUBBER MATERIAL TO COVER JOINTS AND SEAL EDGES. PROTECTO WRAP, BITUTHENE AND NORDEL-TYPAR PERFORMED GENERALLY WELL ENOUGH IN THE LABORATORY TESTS TO INDICATE FIELD PERFORMANCE MIGHT EQUAL OR EXCEED THAT OF THE PRESENT SYSTEM. PROTECTO WRAP AND BITUTHENE WERE GIVEN FIELD TRIAL ON NORTHBOUND AND SOUTHBOUND ROADWAYS RESPECTIVELY OF I-295 STRUCTURES OVER FORE RIVER, SOUTH PORTLAND. UNIROYAL, WITMER 520 AND POLYTOK 165 WERE RECOMMENDED FOR TRIAL ON SIMPLE SPANS. EDCO U-FLEX WAS FOUND TO BE PROMISING FOR PROTECTING STEEL AND PREVENTING LEAKAGE UNDER TRANSFLEX TYPE ELASTOMERIC JOINTS. EVALUATION MUST AWAIT COMPARATIVE FREEZE-THAW (F/T) TESTS USING EXISTING TYPE SEALANTS.
