This study aims to propose a kinetics-based model of the fatigue crack growth rate coupling with temperature, strain level and damage degree for bituminous materials. The fatigue crack length is calculated by the energy-based mechanistic (EBM) approach, and kinetic parameters characterizing the fatigue crack growth rate are determined based on the Arrhenius equation. The results show that the logarithm of fatigue crack growth rate is linear to the inverse of absolute temperature, and the cracking activation energy is independent on strain level and damage degree. Besides, the proposed kinetics-based model can predict fatigue crack growth rate at arbitrary conditions.
