• Abstract:
  Proper calibration of pavement design and rehabilitation performance models to ; conditions in Texas is essential for cost-effective flexible pavement design. The degree of ; excellence with which TxDOT’s pavement design models is calibrated will determine how ; optimally literally billions of dollars of future roadway investment capital will be spent. The ; magnitude of benefits and consequences involved make this research project one of the more ; important research efforts the department has undertaken recently. ; Collection of quality and reliable pavement performance data on a sustained basis is the ; main goal of this project. Inevitably, this presents a perfect opportunity to calibrate and validate ; the current design methods and models for both flexible pavement and overlays. The calibration ; of these models to the Texas local conditions will result in pavement designs that are more ; economical in the long term and that have an increased likelihood of performing as expected.
