Description
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.
