Fatigue Damage Self-Healing Analysis and the Occurrence of an Optimal Self-Healing Time in Asphalt Concrete

Fatigue damage is one of the main distresses responsible for the deterioration of asphalt roads. Self-healing, occurring during rest periods, has been shown to increase the total number of loading cycles. The increase is assumed to depend on the time at which healing is induced and the healing duration. In the first damage stage, in which damage is caused by thixotropy, self-heating and permanent deformation, the recovery is equal to the...
