Description

This guide provides information on what makes a good gravel road surface. Sections of this text have a focus on construction, drainage, surface gravel, and stabilization of roads. The final section covers innovations in the gravel road maintenance and rehabilitation industry. There are new ways of stabilizing roads, new methods of dust control, and different kinds of equipment available for maintenance or rehabilitation of gravel roads. Alternative surface materials such as recycled pavement or blends of recycled and virgin aggregate are being used.

In many cases, gravel roads exist to provide a means of transporting agricultural products in and out of farm fields, timber out of forests, or access remote areas such as campgrounds and lakes. Many gravel roads serve rural residents, as well. Many of these roads will remain unpaved due to very low traffic volume and/or lack of funds to adequately improve the subgrade and base before applying pavement layer(s).

This manual was developed with a major emphasis on the maintenance of gravel surfaced roads, including some basic design elements.

This guide includes a handy list of acronyms, definitions of terms, and appendix with guidance on temporary traffic control for work zones on unpaved roads to include work zone safety measures.
