Review and evaluation of intermediate temperature monotonic cracking performance assessment testing standards and indicators for asphalt mixes

The main objective of this study was to review and evaluate the current monotonic cracking performance assessment tests and indicators. The testing requirements of various test standards were compared. Also, key publications, concepts, calculation methods, physical meaning, and advantages and disadvantages of various performance indicators were documented. In addition, a comprehensive laboratory evaluation was conducted to examine indicators sensitivity to mix compositions, variability, and statistical grouping as well as mix performance ranking. The results showed that the indirect tension test provided better cracking assessment as compared to semi-circle bending tests. In addition, the Weibull cracking resistance indicator was recommended over other performance indicators.
