Vehicle-pavement interaction modelling

This paper presents a new user friendly software architecture that can be used to model the interaction between vehicles and pavements and the effects of dynamic vehicle loading and environmental factors on pavement performance and life. Users can use the software as supplied, or the software’s modular structure is designed to allow users to add-in alternative modules, developed by themselves or others. The intention is to provide a modelling environment that can be used to investigate a wide range of issues in vehicle-pavement interaction without needing the user to be expert in all areas. It is also planned that the software package will be freely distributed, with the code for the modules being open source. The structure of the software and the basic set of modules are presented, along with example results and details of the graphical user interface (GUI) and user-module generation. A case study using the calculations, investigating the effects of static load levels and air suspension maintenance is presented. Additional details of the software are available from http://www.pavementsimulation.org.
