Book Description
A new Mechanistic-Empirical Pavement Design Guide (MEPDG), also known as the 2002 Design Guide, was recently proposed in the United States. The development of such a procedure was conducted by the National Cooperative Highway Research Program (NCHRP) under sponsorship by the AASHTO. The Design Guide is a significant innovation in the way pavement design is performed. A comprehensive evaluation of the MEPDG performance predictions was conducted. It was found that the faulting model produced acceptable predictions, while the cracking model had to be adjusted. The cracking model was recalibrated using the design and performance data for 65 pavement sections located in Minnesota, Iowa, Wisconsin, and Illinois. A prototype of the catalog of recommended design features for Minnesota low volume PCC pavements was developed using the MEPDG version 0.910. The catalog offers a variety of feasible design alternatives (PCC and base thickness, joint spacing and PCC slab width, edge support type, and dowel diameter) for a given combination of site conditions (traffic, location, and subgrade type). It is recognized, however, that version 0.910 is not the final version of the MEPDG. Therefore, the catalog should be updated after the MEPDG software is finalized.

Book Description
As AASH is expected to eventually adopt the MEPDG at its primary pavement design method, it is critical that the SDDOT become familiar with the MEPGD documentation and associated design software. The research conducted under this project was a first step toward achieving this goal.

Book Description
The Minnesota Department of Transportation's (MnDOT) concrete pavement design procedure, RigidPave, is based on the 1981 American Association of State Highway and Transportation Officials (AASHTO) Interim Guide and is entirely empirically-based. The American Cement Pavement Association (ACPA) developed StreetPave based on the Portland Cement Association (PCA) thickness design method with updated information, including a new fatigue model. This study compared RigidPave to StreetPave with a review of the input variables and design inputs used by surrounding departments of transportation. Existing thin (six inches or less) concrete pavements were also evaluated, which included both city and county pavements and test cells at MnROAD. There are two primary differences between the RigidPave and StreetPave: 1) traffic is handled differently and 2) the underlying design methodology. Both are based on time-tested and proven design methodologies and provide generally similar designs. The predicted design lives of the doweled low-volume cells at MnROAD appear to be similar using either StreetPave or RigidPave. The examples provided by cities and counties typically did not contain enough known information, and therefore, required too many assumptions for analysis. The authors recommend that StreetPave is added as an alternate concrete pavement thickness design procedure for city and county projects in Minnesota. Use of the StreetPave is currently allowed by the Virginia Department of Transportation for design of secondary roads. It was also determined that RigidPave has a built-in reliability of approximately 89% due to a factor of safety that is applied to the modulus of rupture. An alternate approach to allowing StreetPave as a design option would be to incorporate the reliability knowledge of RigidPave learned as part of this project.
