STRESS PREDICTION AND LOW TEMPERATURE FRACTURE SUSCEPTIBILITY OF ASPHALTIC CONCRETE PAVEMENTS

FIVE DIFFERENT METHODS OF STRESS COMPUTATION WERE EMPLOYED TO EVALUATE THERMAL STRESSES IN A NUMBER OF DIFFERENT TEST SECTIONS INCORPORATED IN TWO TEST PROJECTS IN WESTERN CANADA. STRESSES WITHIN THE PARTICULAR ASPHALTIC CONCRETES WERE EVALUATED, USING STIFFNESS PROPERTIES DETERMINED BY INDIRECT MEANS, BY EMPLOYING NOMOGRAPHIC PROCEDURES. FRACTURE STRENGTH- TEMPERATURE RELATIONSHIPS WERE ESTABLISHED FOR ASPHALTIC CONCRETE CORES USING THE TENSILE SPLITTING TEST METHOD. OBSERVED CRACKING IN THE TEST PROJECTS WAS COMPARED TO THAT PREDICTED BY THE VARIOUS STRESS ANALYSES USING A POSTULATED FRACTURE CRITERION.
