• Abstract:
  The PAVECHECK data integration and analysis system was developed to merge Falling Weight ; Deflectometer (FWD) and Ground Penetrating Radar (GPR) data together with digital video images of ; surface conditions. In this study Global Positioning System (GPS) was added to the system, and both the ; existing data collection and data processing programs were modified. One goal of this study was to evaluate ; the potential of using the upgraded PAVECHECK system to collect network level pavement condition data ; to assist in pavement rehabilitation planning. GPR data were collected on the entire roadway network for ; Williamson County in the Austin District. Collecting the entire 400 center lane miles took less than 10 days. ; Maps showing the limits of the data collection activities were developed. The upgraded system and the ; outputs from Williamson county are described in this report. The collected data and upgraded software has ; been delivered to district personnel. ; This system has tremendous potential to assist Texas Department of Transportation (TxDOT) engineers ; with future forensic and pavement rehabilitation studies. The PAVECHECK framework can also assist in ; future pavement layer database efforts and in documenting and evaluating the performance of research test ; sections.
