STRENGTH OF BITUMINOUS MIXTURES AND THEIR BEHAVIOR UNDER REPEATED LOADS, PART II

AT THE 1956 MEETING DATA WERE PRESENTED WHICH SHOWED A RELATIONSHIP EXISTING AMONG TEMPERATURE, RATE OF DEFORMATION AND MAXIMUM COMPRESSIVE STRESS FOR A SHEET-ASPHALT MIXTURE. DATA WERE ALSO PRESENTED DEPICTING A RELATIONSHIP AMONG TEMPERATURE, RATE OF DEFORMATION, APPLIED STRESS AND THE NUMBER OF LOAD REPETITIONS NECESSARY TO CAUSE FAILURE. BOTH RELATIONSHIPS WERE DEVELOPED FOR A SHEET-ASPHALT MIXTURE TESTED IN THE UNCONFINED STATE. DATA HAVE NOW BEEN DEVELOPED WHICH INDICATE THAT THE EXPRESSION RELATING TEMPERATURE, RATE OF DEFORMATION, AND MAXIMUM COMPRESSIVE STRESS DEVELOPED FOR A SHEET-ASPHALT MIXTURE TESTED IN THE UNCONFINED STATE, HOLDS TRUE FOR THE SAME MIXTURE TESTED USING VARYING DEGREES OF CONFINEMENT. ALSO, UNCONFINED COMPRESSION TESTS WERE CONDUCTED ON A BITUMINOUS CONCRETE MIXTURE COMPOSED OF A CRUSHED-STONE AGGREGATE WITH 1/2-IN. MAXIMUM SIZE WHICH SHOWED THE VALIDTY OF THE EXPRESSION FOR THIS MIXTURE TYPE. IN ADDITION, REPEATED LOAD TESTS WITH VARYING DEGREES OF CONFINEMENT WERE CONDUCTED ON A SHEET-ASPHALT MIXTURE. THE REALTIONSHIP AMONG TEMPERATURE, RATE OF DEFORMATION, APPLIED STRESS, AND NUMBER OF LOAD REPETITIONS DEVELOPED FOR THE UNCONFINED STATE APPERARED VALID FOR THE CONFINED STATE. /AUTHOR/
