Pavement

This report presents, improvements implemented for pavement response to load models performed during the Austroads project Developments of Pavement Design Models. There is a large diversity of local materials and significant demand for using alternative source materials such as recycled or modified materials. In that context, there is a need to consider each material characteristic in pavement models to better evaluate the critical strains and performance relationships for pavement design. To obtain a better representation of granular behaviour in pavement response, a finite element program has been developed integrating nonlinear behaviour of granular materials.
