Review of a Procedure for Calibrating Unbound Layer Rutting Model in Flexible Airfield Pavements Using Accelerated Pavement Testing Data

Permanent deformation or rutting is one of the failure mechanisms used for designing flexible airfield pavements. Current model used in the Federal Aviation Administration (FAA) design software relates pavement rutting life to vertical strain at the top of subgrade layer. This paper proposes a more fundamental model that can predict the accumulation of permanent deformation in each individual unbound layer. The process for calibrating the proposed model using the accelerated pavement testing data is reviewed in the paper. It was found that vertical strain at the top of unbound layer is a valid option for correlating with permanent deformation. It is believed that the process outlined in this paper can be used to further calibrate the model with extra data sets and eventually lead to a better rutting model for use in mechanistic-empirical airfield pavement designs.
