It may be of interest to researchers and practitioners in the fields of transportation engineering and pavement engineering. The book offers a unique mix of numerical modeling studies, experimental studies, and case studies from industry. This book covers a wide range of topics, from transportation geotechnics, to geomechanics at various length scales, to pavement materials and structures. This volume, entitled “Transportation Geotechnics and Pavement Engineering”, represents the recent advances and technologies in transportation geotechnics and pavement engineering. This book is the fourth volume of the proceedings of the 4th GeoShanghai International Conference that was held on May 27 - 30, 2018.

This report represents Phase II of the UDOT MEPDG implementation study and builds on the Phase I study report completed in 2005 for UDOT. Due to the nature of the data used in model validation, it is recommended that further MEPDG model validation be accomplished in the future using a database that contains HMA pavement and jointed plain concrete pavement (JPCP) exhibiting moderate to severe deterioration. The rutting model was locally calibrated to increase goodness of fit and remove significant bias. With the exception of the new hot-mix asphalt (HMA) pavement total rutting model, all other models were found to be reasonable. The nationally calibrated MEPDG models were evaluated. This was accomplished using data from Long Term Pavement Performance (LTPP) projects located in Utah and UDOT pavement management system (PMS) pavement sections. A key requirement is validation of the MEPDG's nationally calibrated pavement distress and smoothness prediction models when applied under Utah conditions and performing local calibration if needed. The implementation of the MEPDG as a UDOT standard required modifications in some UDOT pavement design protocols (i.e., lab testing procedures, equipment, and protocols, traffic data reporting, software issues, design output interpretation, and others). The objective of this project was to implement the MEPDG into the daily operations of the Utah Department of Transportation (UDOT). Compared to the original version of MEPDG software (Version 0.7), the updated versions (Versions 0.9 and 1.0) are more sensitive to inputs, which shows the evolution of engineering reasonableness.'Highway agencies across the nation are moving towards implementation of the new AASHTO Mechanistic- Empirical Pavement Design Guide (MEPDG) for pavement design.

In this study, the curl/warp effective temperature difference, the PCC coefficient of thermal expansion, and PCC thermal conductivity had the greatest impact on the JPCP and CRCP distresses. Based on the sensitivity plots obtained from the MEPDG runs, the design input parameters were categorized as being most sensitive, moderately sensitive, or least sensitive in terms of their relative effect on distresses. Representative JPCP and CRCP sections in Iowa were selected for analysis. In this comprehensive study, the effect of MEPDG input parameters on the rigid pavement performance is evaluated using the different versions of the MEPDG software (0.7, 0.9, and 1.0) available to date. This paper focuses on the sensitivity study of jointed plain concrete pavements (JPCP) and continuously reinforced concrete pavements (CRCP) in Iowa using the MEPDG software. Initiatives are underway to implement the new mechanistic-empirical pavement design guide (MEPDG) in Iowa.
