Highway agencies across the nation are moving towards implementation of the new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) for pavement design. The benefits of implementing the MEPDG for routine use in Ohio includes (1) achieving more cost effective and reliable pavement designs, (2) lower initial and life cycle costs to the agency, and (3) reduced highway user impact due to lane closures for maintenance and rehabilitation of pavements. Implementation of the MEPDG is a process that requires time and agency resources (staffing, training, testing facilities including equipment, and so on). A key requirement is validating the MEPDG's nationally calibrated pavement distress and smoothness prediction models when applied under Ohio conditions and performing local calibration if needed. Feasibility of using the MEPDG's national models in Ohio was investigated under this study using data from a limited number of LTPP projects located in Ohio. Results based on limited data showed inadequate goodness of fit and significant bias in a number of the MEPDG new HMA pavement and JPCP performance prediction models. Limited recalibration of these models showed promising results indicating that a full-scale recalibration effort using a more extensive database assembled from projects located throughout the state is feasible.

This guide provides guidance to calibrate the Mechanistic-Empirical Pavement Design Guide (MEPDG) software to local conditions, policies, and materials. It provides the highway community with a state-of-the-practice tool for the design of new and rehabilitated pavement structures, based on mechanistic-empirical (M-E) principles. The design procedure calculates pavement responses (stresses, strains, and deflections) and uses those responses to compute incremental damage over time. The procedure empirically relates the cumulative damage to observed pavement distresses.

The objective of this research study was to develop guidelines for portland cement concrete (PCC) material inputs to the AASHTOWare Pavement ME Design program. The AASHTOWare Pavement ME Design is the software program used by the Mississippi Department of Transportation (MDOT) to develop pavement design alternatives based on the mechanistic-empirical pavement design guide (MEPDG) procedure originally developed under National Cooperative Highway Research Program (NCHRP) Projects 1-37A, 1-40D, and 20-07/Task 288 & 327. MDOT has conducted several research projects to support the implementation of the MEPDG and for increasing the accuracy of the distress prediction models calibrated for local conditions and material sources. The current project focuses on PCC material inputs that represent the mix designs, cementitious materials, and the aggregate sources that will be used in future paving projects. This report provides a summary of laboratory test results of 20 mix designs that include five different aggregate sources and four different options for supplementary cementitious materials (SCM) for partial cement replacement. The laboratory test results represent level 1 and 2 PCC material inputs and report the flexural strength, compressive strength, elastic modulus, poisson's ratio, coefficient of thermal expansion (CTE), and percent length change measurements. Strength and modulus data, are reported for 7, 14, 28, and 90 days as required by the MEPDG. The CTE measurements are reported at 28-days, while the shrinkage length change measurements are reported for ages of 7, 11, 14, 21, 35, 63, 119, and 231 days. Level 2 correlation equations were developed based on compressive strength and other index properties to estimate flexural strength and elastic modulus. In general, these models demonstrate a slight deviation for the default level 2 models used in the global calibration of the MEPDG. Level 2 equations were also developed for each aggregate type and it is recommended that future efforts by MDOT for the recalibration of the rigid pavement distress prediction models should examine the sensitivity of these level 2 correlation equations and provide recommendations in the MDOT Design Manual.

Comprehensive and practical, Pavement Asset Management provides an essential resource for educators, students and those in public agencies and consultancies who are directly responsible for managing road and airport pavements. The book is comprehensive in the integration of activities that go into having safe and cost-effective pavements using the best technologies and management processes available. This is accomplished in seven major parts, and 42 component chapters, ranging from the evolution of pavement management to date requirements to determining needs and priority programming of rehabilitation and maintenance, followed by structural design and economic analysis, implementation of pavement management systems, basic features of working systems and finally by a part on looking ahead. The most current methodologies and practical applications of managing pavements are described in this one-of-a-kind book. Real world up-to-date examples are provided, as well as an extensive list of references for each part.

Experimental composite pavements were constructed at MnROAD in Minnesota and the University of California Pavement Research Center at Davis, where the pavements were instrumented and monitored under climate and heavy traffic loadings. A composite pavement consisting of HMA over jointed plain concrete also was constructed in the field by the Illinois Tollway north of Chicago. At the Tollway, extensive field surveys were performed on 64 sections of the two types of composite pavements. This project also evaluated, improved, and further validated applicable structural, climatic, material, and performance prediction models, and design algorithms that are included in the AASHTO MEPDG and DARWin-ME, CalME, NCHRP 1-41 reflection cracking, NCHRP 9-30A rutting, and the Lattice bonding model.

This book presents recent advances in the field of geomaterial and waste management. With high urbanization rates, advancement in technologies, and changes in consumer behavior, wastes generated through the daily activities of individuals and organizations pose many challenges in terms of their management. The studies presented in this book highlight attempts on the part of researchers and practitioners to address contemporary issues in geoenvironmental engineering such as the characterization of dredged sediments, geomaterials and waste, valorization of waste, sustainability in waste management, and various other geoenvironmental issues that are becoming increasingly relevant in today’s world. The studies were selected from papers presented at the 5th GeoChina International Conference, Civil Infrastructures Confronting Severe Weathers and Climate Changes: From Failure to Sustainability, held in Hangzhou, China on July 23–25, 2018.
