Mechanistic– Empirical 2002 Guide for Design of Minnesota Low-Volume Roads: The Future of Pavement Design is Here!

Wednesday, November 12, 2003 - 3:00pm

About the Event

This presentation provided a brief overview of the 2002 Design Guide, a mechanistic-based design procedure developed under the National Cooperative Highway Research Program (NCHRP) 1-37A study and sponsored by AASHTO. The Design Guide represents a major change in the way pavement design is performed.

The mechanistic-empirical format of the Design Guide provides a framework for continuous improvement to keep up with changes in trucking, materials, construction, design concepts, and computers. In addition, guidelines for implementation and staff training to facilitate use of the new design procedure, as well as strategies to maximize acceptance by the transportation community are included.

A recently initiated study, sponsored by the Minnesota Department of Transportation and the Minnesota Local Road Research Board, will adopt this procedure for design of low-volume Portland cement concrete (PCC) roads for Minnesota conditions. A catalog of recommended design features for typical site conditions (location and traffic) will be developed using 2002 design software with recalibrated models.
