MEPDG Local Calibration
| 项目名称： | MEPDG Local Calibration |
| 摘要： | The Missouri Department of Transportation (MoDOT) has always relied on sound engineering for designing new and rehabilitated pavements. The current design approach is the Mechanistic-Empirical Pavement Design Guide (MEPDG), developed under a series of National Cooperative Highway Research Projects (NCHRP). The MEPDG utilizes existing state-of-the-practice mechanistic-based pavement analysis and distress prediction algorithms. Enough time has elapsed to perform a second local calibration cycle. During this interim period, more performance data has been collected from the original field test sections. In addition, newer models have been introduced to the American Association of State Highway and Transportation Officials (AASHTO) Pavements ME Design Guide software that requires a first local calibration. Greater emphasis will be placed on the rehabilitation models. Objectives are as follows: (1) Perform a second local calibration of distress prediction models for existing field test sections; (2) Supplement existing test sections with additional rehabilitation pavement sections; (3) Perform a first local calibration of newer prediction models in the AASHTO Pavement ME Design Program; (4) Update the materials database library with contemporary pavement materials properties, including reclaimed materials; and (5) Fully document the local calibration work, including clear guidance for changing calibration coefficients. Update the user manual. Provide recommendations and precise details of any suggested /incorporated changes. |
