Book Description
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.

Book Description
This synthesis will be of interest to state and local highway personnel who are responsible for the design, construction, and maintenance of road surfaces and to railroad personnel with similar responsibilities associated with highway-rail grade crossings. It will also be of interest to manufacturers and suppliers of pavement and track materials for crossings. It presents information on the current practices related to highway-rail grade crossing surfaces, including the design and selection of crossing surface materials. This report of the Transportation Research Board describes the various types of highway- rail crossing surfaces, and the issues related to design, operation, and maintenance. Design elements include intersection geometry; drainage; special users, such as bicyclists; and descriptions of failures and their causes. Information is presented on crossing material selection factors, including life-cycle costs and on state practices in selection. Funding issues are also discussed.
