Input Parameters of Enhanced VESYS5

VESYS5 is a probabilistic and mechanistic flexible pavement analysis computer program. It predicts the asphalt pavement performance (rutting, fatigue cracking, present serviceability index, etc.) with time. Also, it has been successfully used to analyze asphalt pavement performance under field traffic and under accelerated pavement testing loads. However, it works only in DOS operating systems and routine use is impractical due to its complicated input and output. These defects significantly block the application of VESYS5. In the past year the Texas Transportation Institute has upgraded and enhanced VESYS5 to the Windows (Registered Trademark) version with user-friendly input and output interface. This report summarizes the input parameters of the enhanced VESYS5 program. These input parameters include climate, pavement structure, material properties, and traffic data. In addition, this report also documents the test protocols on material properties such as modulus and permanent deformation. Finally, a case study is provided to demonstrate the inputs and outputs of the enhanced VESYS5.
