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.

The Cal/OSHA Pocket Guide for the Construction Industry is a handy guide for workers, employers, supervisors, and safety personnel. This latest 2011 edition is a quick field reference that summarizes selected safety standards from the California Code of Regulations. The major subject headings are alphabetized and cross-referenced within the text, and it has a detailed index. Spiral bound, 8.5 x 5.5"

This synthesis will be of interest to maintenance managers, maintenance engineers, health and safety officials, those responsible for environmental protection, police, and others concerned with responding to hazardous materials incidents on public highways. Information is presented on the educational, training, and equipment needs of maintenance personnel, as well as on the procedures for response, containment, and cleanup of hazardous materials. This report of the Transportation Research Board discusses the procedures that are required by federal or state regulations and identifies the various response systems and responsibilities in effect in the states. It describes cautions and caveats that are generally recommended with regard to the training and involvement of highway maintenance forces. Awareness training is noted as the primary and necessary requirement for maintenance personnel. Recommendations for improvements to educational procedures are also included.
