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 TxDOT engineers and other transportation professionals.

Towards this goal, this interim report provides a documentation of the work completed in Year 1 of the project including the following: 1) literature review; 2) development of data collection and analysis plans, and 3) field test sections. The MS Access Data Storage System, used for storing and accessing the collected data, is also discussed in this interim report.
