Relationship between triaxial shear strength and indirect tensile strength of hot mix asphalt Conference Paper uri icon


  • Testing conditions for the indirect tensile (IDT) strength test were investigated in order to determine the MohrCoulomb failure equivalency between the triaxial shear strength and the IDT strength. The time-temperature superposition principle was applied to determine equivalent testing conditions. Testing verified that the time-temperature superposition principle continues to hold at large failure strains. A predictive technique to obtain the cohesion (c) of an asphalt mixture based on the IDT strength was studied and the overall ratio of (c) to IDT strength turned out to be 1.73, which agrees very well with the findings by other researches. The error associated with the prediction of (c) varied between 0.9 to 38% for individual mixtures, averaging less than 21%.
