STIFFNESS OF ASPHALT CEMENTS EVALUATED BY COMPRESSION

FROM THE EXPLORATORY DETERMINATIONS OF STIFFNESS, CONDUCTED OVER THE TEMPERATURE 5 TO -15C (41 TO 5F), IT IS CONCLUDED THAT THE COMPRESSION TEST DESCRIBED WILL BE USEFUL FOR EVALUATING THE RHEOLOGICAL PROPERTIES OF ASPHALT CEMENTS AT LOW ATMOSPHERIC TEMPERATURES. THE DATA CAN BE USED TO COMPARE THE STIFFNESS OF DIFFERENT ASPHALTS AND DIFFERENT GRADES OF EACH ASPHALT AT A CONSTANT RATE OF STRAIN. ALSO, THE DATA INDICATE THE TEMPERATURE SUSCEPTIBILITY OF EACH KIND AND GRADE OF ASPHALT AT THE LOW TEMPERATURES. THE DIFFERENCES IN STIFFNESS OF THE 6 ASPHALTS FOUND BY THIS INVESTIGATION SHOULD LEAD TO AN EXPLANATION OF CERTAIN LOSSES IN SERVICEABILITY EXPERIENCED IN BITUMINOUS PAVEMENT SUBJECTED TO HEAVY TRAFFIC AT LOW ATMOSPHERIC TEMPERATURES. /AUTHOR/
