This Strategic Highway Research Program (SHRP) report is a training supplement for material in "Pavement Maintenance Effectiveness" (SHRP-H-358) and "Development of a Procedure to Rate the Application of Pavement Maintenance Treatments" (SHRP-H-322). This report suggests some immediate improvements in current pavement maintenance techniques, such as chip seals, slurry seals, crack sealing in asphalt pavement; and undersealing, and joint and crack sealing in Portland Cement concrete pavements. Researchers request that highway maintenance departments continue to track and log pavement maintenance data.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
