COMPREHENSIVE SYSTEM FOR ESTIMATION OF LOW-TEMPERATURE CRACKING FREQUENCY OF FLEXIBLE PAVEMENTS

A COMPREHENSIVE METHODOLOGY FOR PREVENTING OR CONTROLLING ONE OF THE MOST COMMON DEFECTS OF ASPHALT PAVEMENTS IN CANADA - LOW-TEMPERATURE CRACKING, IS DESCRIBED. FACTORS OF RECOGNIZED SIGNIFICANCE ON THE LOW-TEMPERATURE CRACKING FREQUENCY ARE REVIEWED AND THEIR THEORETICAL INFLUENCE ON THE FREQUENCY POSTULATED. THE BEST INDIRECT METHOD FOR DETERMINATION OF ONE OF THESE FACTORS, STIFFNESS MODULUS, IS IDENTIFIED ON THE BASIS OF EXTENSIVE LABORATORY AND FIELD INVESTIGATIONS. PREDICTION OF LOW-TEMPERATURE CRACKING FREQUENCY OF NEWLY PLANNED ASPHALT CONCRETE PAVEMENTS IS BASED ON A MATHEMATICAL MODEL INCORPORATING ALL IMPORTANT VARIABLES. A NEW TESTING METHOD FOR CONTROLLING LOW- TEMPERATURE RESPONSE OF BITUMINOUS MATERIALS IS PROPOSED AND EVALUATED. /AUTHOR/
