Guidelines for Developing Input Parameters of Enhanced VESYS5 Program (9-1502-01-P5)

VESYS5 is a probabilistic and mechanistic flexible pavement analysis computer program. It predicts asphalt pavement performance (rutting, fatigue cracking, present serviceability index ([PSI], etc.) over time. Also, it has been successfully used to analyze asphalt pavement performance under field traffic and under accelerated pavement testing loads. In the past year the Texas Transportation Institute has upgraded and enhanced the VESYS5 program to the Windows version with user-friendly input and output interfaces. This report documents the guidelines for developing the input parameters for the enhanced VESYS5 program.
