"Asphalt Pavement Fatigue Cracking Modeling." by Yongqi Li
Fatigue is a major structural distress that leads to a reduction in the serviceability of asphalt pavements. In a mechanistic pavement design, asphalt fatigue cracking is considered as one of the three design criteria along with rutting and low-temperature associated cracks. The successful application of this design method to practice thus relies on a reliable crack prediction model.
