EXPERIMENTAL DESIGN, PLANNING, AND ANALYSIS OF PAVEMENT TEST SECTIONS FOR THE TEXAS MOBILE LOAD SIMULATOR

The project was undertaken to assist with the design, planning, and analysis of pavement test sections for future use with the newly developed Texas Mobile Load Simulator. It specifically addresses the type, number, and positions for strain and pressure sensors in the test sections. In the project, the authors conducted two full factorial experiments on test sections built by the Texas Department of Transportation in Victoria, Texas. Using a conventional dump truck, they collected data from various makes of strain and pressure sensors embedded in the pavement at different positions and depths. These data were analyzed to determine variability characteristics by constructing a quadratic response surface model estimated by least squares regression. This analysis was then used to assess precision of measurements, with the model used to compare measured values with theoretically predicted values for an assessment of accuracy.
