Book excerpt: The National Cooperative Highway Research Program (NCHRP) 1-37A project has developed a guide for the design of new and rehabilitated pavement structures based on mechanistic-empirical principles. The guide is commonly known as Mechanistic-Empirical Pavement Design Guide (MEPDG). The current American Association of State Highway and Transportation Officials (AASHTO) pavement design method is based on the empirical relationships that were developed from the AASHO Road Test done near Ottawa, Illinois (1958-1960). The new NCHRP design guide, based on mechanistic-empirical principles, combines the advantage of advanced analytical modeling capabilities and field performance observed in the pavements. The transition from empirical to mechanistic-empirical methods is challenging as the implementation of the new design guide requires site specific material, traffic and climatic inputs for accurate analysis and prediction of pavement response and performance. The objective of this work is to assist the Kansas Department of Transportation in implementation of the new design guide by developing a data base of material inputs required by MEPDG software for asphalt concrete mixes. The comparison of measured and predicted dynamic moduli for the samples compacted at a target air void of 7% showed that the measured values were always higher than the values predicted by the Witczak model when the model used the binder data either derived from the laboratory tests or the values recommended by the NCHRP Guide. The Hirsch model predicted moduli that were even lower than those predicted by the Witczak model. The ratio between the measured and the predicted moduli increased when the air voids of the samples approached 4.0%. For all but two asphalt mixes, the predicted Indirect Tensile Strength (ITS), at -10°C was smaller than the average measured ITS, the error being as much as 50%. The models included in the MEPDG severely overestimate the creep compliance of Kansas Superpave mixes at -10°C. The predicted values are about three times the corresponding measured values.

Available in PDF, EPUB and Kindle. Book excerpt: While the 1986 and 1993 editions of the AASHTO Guide for the Design of Pavement Structures recognized the importance of moving towards machanistic based design procedures, limitations on computer speed, modeling techniques, and pavement performance data made the implementation of mechanistic based designs difficult at that time. The 2002 Design Guide will contain procedures for the design and analysis of all types of new and rehabilitated pavement systems. Where feasible, the design methodologies for the various pavement types will be integrated, such that the design procedure does not inherently favour any particular type of pavement. Further, the mechanistic-empirical design procedure to be included in the 2002 Guide will allow the designer to evaluate the effects of variations in materials on pavement performance. This paper discusses the new data input requirements for the design procedures described in the 2002 Guide. For the covering abstract of this conference, see ITRD number E211217.

This book was released on 2004 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current 1993 AASHTO "Design Guide for Design of Pavement Structures" uses resilient modulus to assign an "a" coefficient to hot mix asphalt (HMA) to determine the required thickness of the HMA layer for a given traffic loading and subgrade support condition. There are several methods to determine the modulus of a mix for use in determining the "a" coefficient. Modulus results are a function of the test method and curing conditions. Therefore, the test method and curing conditions would have an effect on the "a" coefficient used in thickness design and, hence, the thickness of the pavement layers. A need was voiced by the Kansas Department of Transportation (KDOT) to evaluate the available test methods for determination of the stiffness properties of HMA.
