Effectiveness and Guidance of Aggressive Rehabilitation of Gravel Roads
Maintenance of Iowa's unpaved road system is a major issue to Iowa's local agencies and the general public. Part of this maintenance is the major rehabilitation or regrading of these roads once the roads become too wide caused from heavy traffic loading. Methods to do this vary across the state due to soil types, available manpower and equipment, and even public opinion. It is widely known that proper width and shape is essential to the drainage of and long term performance of a gravel road. This idea would summarize the best practices for this type of activity based upon Iowa's different areas and try to quantify the gain in performance of gravel roads that are narrowed back to their original design width and have proper crown.
