Gravel Roads: Maintenance and Design Manual. South Dakota Local TransportationAssistance Program (SD LTAP)

摘要

The purpose of this manual is to provide clear and helpful information for doinga better job of maintaining gravel roads. It is recognized that very little technical help is available to small agencies that are responsible for managing these roads. Gravel maintenance has traditionally been more of an art than a science and very few formal standards exist. This leads to many arguments between grader operators, managers, and motorists over questions such as: What is enough surface crown. What is too much. What causes corrugation. This manual contains guidelines to help answer these and other questions about the maintenance of 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.
