OC: Design and Maintenance of Gravel Roads
This eight-hour engineering course addresses themaintenance and design of gravel roads. Unpaved surfaces make up a sizablepercentage of both domestic roads, as well as roads abroad; therefore, theadministration and maintenance of these road systems can be an enormous task.Most of the maintenance duties of these road systems fall on local authorities,although much of the remaining responsibilities lie with state highway agencies.
This course provides an overview of the administration,maintenance and design, reshaping and rehabilitation, and constructionconsiderations of gravel roadway systems. Special topics include drainage,erosion and control, windrows, superelevation, as well as other special areasof concern.
