Permanent deformation behavior of unbound granular materials and rutting model development
The rutting damage model as incorporated into the AASHTO’s mechanistic-empirical (M-E) pavement design approaches (i.e. Pavement ME Design) was found to produce inadequate rut estimates in unbound aggregate base/subbase layers by discounting the contribution of stress state from the original Tseng …

Evaluation and modeling of repeated load test data of asphalt concrete for mechanistic-empirical flexible pavement design
… Pavement Design Guide (MEPDG) uses a power model that incorporates Dynamic Modulus (DM) as a factor in predicting rutting performance of asphalt concrete. The rutting model is empirical and the rutting profiles obtained from the model are largely based on the adjustment of calibration …

Characterization of traffic load and local calibration of the MEPDG for New Mexico
… alligator cracking, and longitudinal cracking models are calibrated. In calibration methodology, the target is fixed to reduce the residual sum of squared errors, defined by the difference between predicted and measured distress, so that any bias is eliminated and precision is increased. The …
