BRIDGE DECK MEMBRANES, EVALUATION AND USE IN CALIFORNIA

LABORATORY TESTS USED TO SCREEN BRIDGE DECK MEMBRANES ARE (1) TENSION ON THE CRACK BRIDGING; (2) PUNCTURE ABILITY TO WITHSTAND PAVING OPERATIONS, AND (3) BENDING OR COLD TEMPERATURE DUCTILITY WITH AND WITHOUT HEAT AGING. NONE OF THE TESTS, HOWEVER, ARE KNOWN TO BE RELATED TO THE SERVICE LIFE OF THE MEMBRANE. RESULTS OF COMPARING FIELD AND LABORATORY TESTS ARE GIVEN. IT WAS FOUND THAT A 240 DEG F ASPHALT CONCRETE PAVEMENT COULD CAUSE A RISE IN TEMPERATURE OF THE MEMBRANE TO ABOUT 170 DEG F FOR APPROXIMATELY 3 MINUTES. HOWEVER, WINDROWING OF THE PAVEMENT WAS FOUND TO MELT SOME MEMBRANES DUE TO THE LONG TERM SUSTAINING OF HIGH TEMPERATURE. TESTS WERE MADE USING THE ELECTRICAL RESISTANCE METHOD AS AN INDICATOR OF IMPERMEABILITY OF A MEMBRANE. IT WAS FOUND THAT THE ELECTRICAL RESISTANCE WILL VARY WITH TIME. THE MATHEMATICAL RELATIONSHIP BETWEEN RESISTANCE AND TIME IS GIVEN FOR 8 FIELD TESTS. /FHWA/
