There are over 1.6 million miles of unpaved roads (53% of all roads) in the United States. In some nations, the road network is predominantly unpaved and generally consists of gravel roads. The purpose of this manual is to provide clear and helpful information for doing a better job of maintaining gravel roads. This manual is designed for the benefit of elected officials, managers, and grader operators who are responsible for designing and maintaining gravel roads. The information provided in this manual is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
