| 摘要： | This report presents the research effort to develop an implementation plan for the NCHRP 1-37A Mechanistic- Empirical Pavement Design Guide (MEPDG). This research encompasses both flexible and rigid pavements in new and rehabilitation projects. The project includes the study of current design practices followed by the NCDOT and the design practices followed by the MEPDG. The MEPDG is a sophisticated tool used to predict the performance of pavements and requires more rigorous inputs than any other earlier design procedures. Because the distress prediction models included in the MEPDG were calibrated using limited national databases, it is critical to calibrate the design methods and models using locally available input and performance data. The implementation plan developed during this project provides detailed recommendations for the steps necessary for the local calibration and validation of the MEPDG procedures. One important issue in the successful implementation of the MEPDG is the sensitivity analysis of the input data and the prediction using local databases. The Long-Term Pavement Performance (LTPP) database plays a significant role in this study. / NOTE: Final rept.
