PaveSim

Abstract

PaveSim, a dynamic simulation environment, has been created to help develop performance-based operations policy. Integrated into PaveSim is another simulation program called TruckSim, which was developed at the University of Michigan to model heavy vehicles. Using the dynamic wheel loads from TruckSim, PaveSim simulates the performance of jointed concrete pavements. RigidPav, a finite element program, performs the detailed calculation of deflections and stresses in the pavement. Within the PaveSim environment it is possible to quickly vary vehicle parameters such as number of axles and axle spacing, suspension type and characteristics, and payload and distribution. We can also estimate the effects on pavement life of pavement characteristics such as thickness, subgrade support, and joint types. This report presents an overview of the PaveSim environment and its user interface. Most of the report is written as a PaveSim tutorial to be used by pavement designers and policymakers in state and federal departments of transportation.
