• Abstract:
  In this project, researchers conducted an extensive sensitivity analysis of the new Mechanistic-Empirical Pavement Design Guide, the development of default input files, and a review of current procedures to develop an implementation strategy and justification of the new pavement design guide. The sensitivity analysis was conducted for the primary design modules, for each level of input data (e.g., Level 1, 2, and 3). The objective of the sensitivity analysis was to determine to what degree the input parameters affect the performance of the initial design. In addition to the sensitivity analysis, the Texas Department of Transportation's (TxDOT's) current pavement design approach was reviewed and contrasted to the design guide to determine what additional tests or other changes will be needed for the implementation of the new design guide. Initial input materials parameters and regional calibration values were developed using available materials information and pavement performance data in TxDOT and research projects.
