BENDING STRENGTH OF ASPHALTIC CONCRETE

THIS REPORT IS CONCERNED WITH THE FLEXURAL FATIGUE STRENGTH OF ASPHALTIC CONCRETE SURFACING MIXTURES AS MEASURED BY A REPETITIVE DEFLECTION TEST ON DISC-SHAPED SPECIMENS, AND THE STATIC BENDING OR TENSILE STRENGTH AS DETERMINED FROM A MODIFIED COHESIOMETER TEST. RESULTS WERE OBTAINED FOR LABORATORY-PREPARED SPECIMENS WITH VARYING ASPHALT CONTENT, ASPHALT GRADE AND ASPHALT SOURCE. CORRELATIONS BETWEEN THE TWO TEST METHODS ARE PRESENTED. TRENDS ARE NOT CONSIDERED TO BE WELL-DEFINED, ALTHOUGH IT APPEARS THAT BENDING STRENGTH INCREASES WITH ASPHALT VISCOSITY. IT IS ALSO INDICATED THAT THE COHESIOMETER TEST CAN PROVIDE AN INDEX OF BENDING STRENGTH WHICH CAN BE RELATED TO A STRENGTH COEFFICIENT FOR USE IN FLEXIBLE PAVEMENT DESIGN. TEST DATA ARE PRESENTED FOR A NUMBER OF FIELD TEST SECTIONS UNDER STUDY IN THE PAVEMENT PROJECT, BUT THESE RESULTS HAVE NOT BEEN SUBJECTED TO THOROUGH ANALYSIS. /BPR/
