VESYS G-A COMPUTER PROGRAM ANALYSIS OF N-LAYERED FLEXIBLE PAVEMENTS

This report contains the operating instructions for the computer program VESYS G that is used to predict the responses, distress, and performance of N-layered flexible pavements. VESYS G was developed by integrating a version of the CHEVRON N-layer computer program, modified at the University of Utah to be probabilistc and viscoelastic, with the FHWA VESYS IIM structural subsystem. Primary (stationary load) response. General (moving load and temperature) repsonse. Damage (cracking, rutting, and roughness). Performance (serviceability). VESYS G basically replaced the three-layer primary response model of VESYS IIM with an N-layer one. These changes and a sensitivity analysis are presented.
