Evaluating fatigue behavior of asphalt mixtures under alternate tension-compression loading model using new alternate biaxial splitting method

- An alternative biaxial splitting (ABS) fixture has been developed.
- Fatigue behavior of asphalt mixtures under a tension-compression loading mode has been analyzed.
- The laboratory fatigue life of the ABS test samples was longer than that of the IDT test.
- The creep effect of compressive stress produced increased fatigue life of asphalt mixtures.
