Thixotropic Behavior of Paving-Grade Bitumens under Dynamic Shear
Publisher: American Society of Civil Engineers
Abstract: A material exhibits thixotropic behavior if its apparent viscosity decreases under stress and if it recovers its initial viscosity when unloaded. This thixotropy is well defined for fluids, but it is not well understood ...
Continuum Damage Approach to Asphalt Concrete Fatigue Modeling
Publisher: American Society of Civil Engineers
Abstract: A nonlocal damage model is proposed to predict the behavior of pavement fatigue cracking. This constitutive relation has been implemented in a finite-element code, along with a self-adaptive jump-in-cycle procedure for ...
