FATIGUE AND TENSILE CHARACTERISTICS OF BITUMINOUS PAVEMENTS AT LOW TEMPERATURE

PAVEMENT MUST PERFORM THROUGH A WIDE RANGE OF TEMPERATURES. MOST TEST METHODS AND MIX DESIGN PROCEDURES ARE BASED ON ELEVATED TEMPERATURES. DUE TO THE DRASTIC CHANGE IN PHYSICAL CHARACTER OF ASPHALT AS TEMPERATURE DECREASES, THE CRITICAL SERVICE CONDITIONS MAY BE AT LOW TEMPERATURES. THIS RESEARCH APPLIED A SPLIT CYLINDER TENSION TEST TO TYPICAL BITUMINOUS PAVEMENT MIXES AT VARIOUS LOW TEMPERATURES. AS FURTHER VERIFICATION OF THE IMPORTANCE OF LOW TEMPERATURE CHARACTER, A SERIES OF FLEXURE FATIGUE TESTS WERE CARRIED OUT. THE TEMPERATURE RANGE OF ZERO TO 40 DEGREE F WAS INVESTIGATED. THE EFFECT OF ASPHALT CONTENT AND GRADE IS INCLUDED. DUE TO THE NON-HOMOGENEOUS NATURE OF BITUMINOUS-AGGREGATE MIXTURES, THE RESULTS OF THE SPLIT CYLINDER TEST ARE IN TERMS OF WORK TO CAUSE FAILURE RATHER THAN UNIT TENSION STRESS /AUTHOR/
