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 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 comprehensive work plans and strategies that were developed to calibrate and validate the M-E models and the associated software. As a minimum, the calibration and validation plans covers the following M-E models and associated software:
• The FPS.
• The TxACOL.
• The TxM-E.
• The M-E PDG.
As discussed in this interim report, these strategic work plans were devised on the premise that data for calibrating and validating these M-E models/software will predominantly come from the Project 0-6658 MS Access Data Storage System (DSS). Accordingly, the DSS is also discussed in this interim report. Demonstration examples of the software (FPS, TxACOL, and M-E PDG) runs are also included in the report.
