TL;DR: In this paper, an energy-based mechanistic approach is applied to determine crack length and the pseudo J-integral is adopted to calculate crack growth rate in asphalt binder, which has a significant influence on fatigue cracking resistance of asphalt pavements.

TL;DR: In this paper permanent deformation and cracking of asphalt mixtures are common distresses of pavement structures and these two damage processes are usually coupled and occur simultaneously, and the evolution of the two processes is described.

TL;DR: In this article, the authors proposed a kinetics-based model of fatigue crack growth rate coupling with temperature, strain level and damage degree for bituminous materials and showed that the model can predict the growth rate at arbitrary temperature and strain level.

TL;DR: In this paper, a pseudo J-integral Paris' law model and probability theory are combined to establish a stochastic fatigue damage model for viscoelastic materials, and the model can track the entire fatigue damage process of viscous materials by coupling the variability with the fatigue mechanism.

TL;DR: In this paper, a modified viscoelastic strengthening coefficient with fatigue cracks (VSC-f) model was proposed to predict the shear modulus for an asphalt-filler composite system at different strain levels, temperatures, filler contents and damage levels.
