Abstract:Local calibration of the fatigue cracking model used in the AASHTO Pavement Mechanistic-Empirical (ME) software is critical to accurately prediction of the performance of jointed plain concrete pavement (JPCP). Although calibration involves optimizing coefficients used in the model, other design inputs such as time to friction loss can have a significant impact on pavement performance. The degradation of friction between the concrete and supporting layers is a critical input since it indicates deterioration of… Show more
