Bigge Crane Megaload Permit Issued

A permit has been issued for a megaload to travel from Idaho through Montana to Great Falls. The move, planned for seven stages, will travel at night to minimize travel disruptions to others along the route. MORE INFORMATION

Numerical Modeling and Design Model Development for Geosynthetic Reinforced Flexible Pavements (GRFP)

Provided below are links to a number of documents prepared by Montana State University for the Montana Department of Transportation. These documents were prepared for a research project related to the development of a design model for geosynthetic reinforced flexible pavements. Two reports were prepared for the project.

The report, Numerical Modeling of Geosynthetic Reinforced Flexible Pavements, describes the theoretical numerical modeling work performed.

The report, Mechanistic-Empirical Modeling and Design Model Development for Geosynthetic Reinforced Flexible Pavements and its appendix, describe how the numerical model was used to develop a mechanistic-empirical pavement analysis model, from which a design model was developed.

MSU-GRFP_Design_Model.xls, is a spreadsheet program that performs the calculations described in this report. This report also contains a design guide describing the use of the spreadsheet program. The appendix contains output from DARWin life-cycle cost analysis examples contained in the design guide.

A training program has also been developed. This training program can be accessed using the links below.
