Abstract:

The objective of this study is to integrate the accelerated pavement test technologies of Texas, Louisiana and other participating States with modeling capabilities developed by the FHWA in their Truck Pavement Interaction (TPI) program. The pavement damage predictions have been made using a calibrated version of the VESYS 5 mechanistic/predictive model, which have been under development by the FHWA for the past two decades. During the course of this project, VESYS5 has been calibrated with the accelerated pavement test (APT) data from Texas. In this project, UTEP's role has been to develop a finite element model that can be used to predict permanent deformation of the pavement under NAFTA truckloads. These models, which have been primarily developed using finite element software package ABAQUS, provide tremendous flexibility that is not possible with VESYS5. For example, the three-dimensional aspects of loading, as well as the impact of the load induced nonlinear nature of material properties on the response of the pavement are rigorously modeled.
