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.
This synthesis will be of interest to maintenance managers, maintenance engineers, and others concerned with the periodic problems associated with the day-to-day maintenance of highways. Information is presented on discovery and response systems applicable to short-term responsive maintenance needs. The development and implementation of short-term responsive maintenance systems (STRMS) can be effective in handling permanent or temporary repairs. This report of the Transportation Research Board describes and discusses the short-term responsive maintenance systems in effect in several states. It describes how these special maintenance needs are detected, reported, evaluated, and managed, and notes how new technology can assist maintenance managers.
"This synthesis examines current performance-based management practices that are applied by state departments of transportation (DOTs) in highway maintenance and operations (M&O). Past studies have focused on the elements that make up a performance-based M&O approach, such as condition ratings, levels of service, performance measures, and threshold values. This study focuses on how state DOTs actually use performance-based measures to manage their highway programs."--Preface.
