Evaluation of Permanent Deformation Models for Flexible Pavements Using Accelerated Pavement Testing
Several models are currently available for the prediction of permanent deformation in flexible pavements. These models are intended for different analysis conditions and require extensive calibration and validation before use. The aim of this article is to evaluate the permanent deformation models incorporated in a Swedish analysis tool (i.e., ERAPave ME) for flexible pavements. Measured response and performance data from an accelerated pavement testing using heavy vehicle simulator is used for this purpose. Pavement response is computed using a multi-layered linear elastic analysis tool while stress-dependency is accounted in the prediction of permanent deformation. A general good agreement has been observed between measured and computed responses. The same is true for observed and predicted permanent deformations. The permanent deformation prediction is achieved using model parameters that are unique to each layer and loading level.
