Overweight (OW) loads typically require innovative truck configurations that distribute the load more efficiently than traditional five-axle configurations, potentially reducing the infrastructure consumption. Therefore, it becomes important to understand the feasibility of such alternative vehicle configurations, assess the associated pavement and bridge consumption, and estimate necessary user fees for maintaining the infrastructure. This project’s objective was to develop methodology to quantify the relative consumption of different axle loads and vehicle configurations on pavements and bridges. Guidelines were developed for more infrastructure-friendly vehicle configurations based on both structural and economic analyses. Alternative vehicle configurations are proposed based on the results obtained by considering varying factors such as axle type, distance between axles, and load per axle. In addition, a cost recovery structure was developed that adequately funds repairs to roads used by OW trucks. Finally, recommendations for implementing the findings of this study into a coastal corridor in Texas were developed.
