MINNESOTA'S DESIGN GUIDE FOR LOW VOLUME AGGREGATE SURFACED ROADS. FINAL REPORT

This Soil Factor Design Method was written for counties, townships, and municipalities for use in designing aggregate roads. Although many design methods for aggregate roads exist, most require thorough soil identification and soil strength testing. Since most local agencies do not have the means to perform elaborate testing of soils and because they are familiar with soil factors, this design method should be helpful. This procedure requires soil identification, traffic counts and rational judgement. At present the Minnesota Department of Transportation does not have a design method for aggregate roads. It is not the intention of this manual to change the present legal load limits for gravel roads. For those who would like a more thorough design method, or more background information on aggregate roads, the method includes information on the use of the U.S. Forest Service Aggregate Surface Design Guide. Also included is information regarding compaction, drainage, frost action, geosynthetic use, lime stabilization, and an appendix with sample problems based on the Soil Factor and Forest Service design methods.
