• Abstract:
  The implementation of North American Free Trade Agreement (NAFT A) opened the borders to international traffic coming from both Canada and Mexico. As a consequence, highway networks will be subjected to trucks with new axle configurations and heavier axle loads, causing concern on the impact of super-heavy vehicles on highway's infrastructure. This pooled fund study is aimed at providing these tools. The workhorse of this effort has been the VESYS 5 pavement damage prediction model calibrated with local materials and performance data. Despite the successes in VESYS for rutting and performance predictions in pavement systems, some limitations exist, such as difficulties in incorporating new or more advanced constitutive models into VESYS. Finite Element techniques, on the other hand, generally possess flexibility in the adoption of new emerging constitutive models and can be used in two- and three-dimensional configurations. Under this research project a tool with the capacity to calculate pavement distress under any type of traffic load and to make a comparison of the level of distress caused by a standard and a non-standard truck has been developed. The finite element models are then interfaced with a GIS map for the determination of the potential damage along a corridor.
