Texas Flexible Pavements and Overlays: Year 5 Report—Complete Data Documentation

Proper calibration and validation of pavement design and performance models to Texas conditions is essential for cost-effective flexible pavement design, performance predictions, and maintenance/rehab strategies. The veracity of the calibration of the Texas Department of Transportation pavement design models will determine how optimally billions of dollars of future roadway investment capital will be spent. For proper calibration/validation and tangible benefits, quality and reliable pavement performance data should be collected on a sustained basis. In order to accomplish the task of data collection, this five-year project was initiated to develop a comprehensive data storage system (DSS) of material properties and performance data for Texas flexible pavements and overlays. The objective of the project was to collect materials and pavement performance data on a minimum of 100 highway test sections around Texas. In total, the DSS comprises 112 highway test sections scattered across Texas. This report documents all the work performed, methods used, and results completed throughout the project. These tasks included gathering design and construction data of test sections, executing laboratory and field performance testing, collecting traffic and climate data, and developing the data repository system consisting of the DSS and a raw data storage system (RDSSP). Finally, recommendations for the continuation of data collection to enable further calibration of performance models are given.
