• Abstract:
  VESYS5 is a probabilistic and mechanistic flexible pavement analysis computer program. It predicts the asphalt pavement performance (rutting, fatigue cracking, present serviceability index PSI, etc.) with time. Also, it has been successfully used to analyze the asphalt pavement performance under the field traffic and under accelerated pavement testing loads. However, it works only in DOS operation systems and routine use is impractical due to its complicated input and output. These defects significantly block the application ofVESYS5. In the past year the Texas Transportation Institute has upgraded and enhanced the VESYS5 to the Windows® 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 property. Finally, a case study is provided to demonstrate the inputs and outputs of the enhanced VESYS5.
