A listing of special products which have been evaluated by state highway or transportation departments and based upon information received by the AASHTO Subcommittee on Materials and maintained in a computerized file by the Materials Division, Federal Highway Administration.
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.
Intended to provide background material for use by AASHTO and others in the development of a national surface transportation program and policies to serve America through the first two decades of the next century.
