Abstract:This five-year project was initiated to collect materials and pavement performance data on a minimum of 100 highway test sections around the state of Texas, incorporating both flexible pavements and overlays. Besides being used to calibrate and validate mechanistic-empirical (M-E) design models, the data collected will also serve as an ongoing reference data source and/or diagnostic tool for Texas Department of Transportation engineers and other transportation professionals. Toward this goal, this second interim report provides documentation of the work performed from Year 1 through Year 5 of this project, focusing on Phases II and III activities, including the following: (a) collection, processing, and analysis of laboratory and field data; (b) data population and update in the data storage system (DSS) and raw data storage system for the project 0-6658 (RDSSP), respectively; (c) development of M-E calibration plans and guideline; and (d) preliminary calibration of the M-E models and software to Texas conditions using the collected data in the DSS.
