This field guide is organized to identify visual signs of problems associated with CAUSES and SOLUTIONS for the most commonly encountered road problems.

Over 1.6 million miles of dirt and gravel roads exist within the United States providing a vital part of the nation's transportation system. An environmentally sensitive road maintenance practice is a practice that when implemented reduces the adverse effect of a road on the environment by treating the cuase of the problem and is in keeping wtih the natural landscape. This illustrated field guide provides examples of environmentally sensitive maintenance practices, which if implemented reduce erosion and sediment, maintain subsurface hydrologic connectivity, restore drainage density to more natural conditions, and eliminate diversion potential. It is organized to identify visual signs and problems associated with CAUSES and SOLUTIONS for the most commonly encountered road problens (road surface, ditch, cutbank, etc.) Highway inspectors, public works construction inspectors, to include some construction and building inspectors and engineers that must meet compliance with specifications, building codes, and other regulations, Additionally, City engineers, concrete masonry contractors, road maintenance specialists and workers, and technicians, as well as County Road Supervisors may ber interested in this volume. Students pursuing degree programs for Civil Engineering or certificates of study for Industrial Maintenance Technology or Public Works training in clases such as Roadway Asset Management Essentials, or Inspecting Pavement Markings or certified Public Infrastructure Inspector courses may be interested in this print field guide as a handy reference.

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 Low-Volume Roads Engineering Best Management Practices Field Guide is intended to provide an overview of the key planning, location, design, construction, and maintenance aspects of roads that can cause adverse environmental impacts and to list key ways to prevent those impacts. Best Management Practices are general techniques or design practices that, when applied and adapted to fit site-specific conditions, will prevent or reduce pollution and maintain water quality. BMPs for roads have been developed by many agencies since roads often have a major adverse impact on water quality, and most of those impacts are preventable with good engineering and management practices. Roads that are not well planned or located, not properly designed or constructed, not well maintained, or not made with durable materials often have negative effects on water quality and the environment.
