... when the loading is discontinued. Fatigue loading results in a decrease in the asphalt binder’s modulus related to reversible phenomena such as thixotropy, healing, and self-heating, in addition to irreversible permanent fatigue damage. The study of thixotropy is important to better characterize damage...
