| 摘要： | Proper calibration of mechanistic-empirical (M-E) design and rehabilitation performance models to meet Texas conditions is essential for cost-effective flexible pavement designs. Such a calibration effort would require a reliable source of pavement material properties and performance data collected on a sustained basis. In this study, the researchers developed a comprehensive data storage system (DSS) containing material properties and performance data for flexible pavement and overlaid test sections in Texas. A minimum of 100 flexible pavement and overlay sections across Texas were monitored, and data were collected for subsequent population of the DSS to: (1) Serve as a data source for the calibration of the Texas M-E models and design software, such as the Texas M-E pavement design system (TxME). (2) Serve as an ongoing reference data source and diagnostic tool for Texas Department of Transportation (TxDOT) engineers and other transportation professionals. |
