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.

All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.

This reference book communicates the basic theoretical knowledge, the practical requirements and experience for designing, mapping, calculating and checking roads and the planning process overall and at the same time reveals important development trends. The book is guided by the current rules and regulations in Germany, it universalizes this knowledge and also integrates important current research results in road design processes. In order to restrict the scope of the book, it only deals with the theoretical principles and knowledge, and the practical experience for designing rural roads, i.e. the special features of urban roads are not mentioned here. This clear separation primarily results from the different principles and rules and regulations. The terms, definitions, abbreviations and formula symbols are based on German usage, but can be transferred to an international framework without any difficulties. The work is particularly designed to be a course book for students of road design. As a reference book, it supports the ongoing training process for road transportation engineers in planning offices and public bodies. Any specialist working in the transportation sector can use it as a reference book.

TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

Roads matter to people. This claim is central to the work of Penny Harvey and Hannah Knox, who in this book use the example of highway building in South America to explore what large public infrastructural projects can tell us about contemporary state formation, social relations, and emerging political economies.Roads focuses on two main sites: the interoceanic highway currently under construction between Brazil and Peru, a major public/private collaboration that is being realized within new, internationally ratified regulatory standards; and a recently completed one-hundred-kilometer stretch of highway between Iquitos, the largest city in the Peruvian Amazon, and a small town called Nauta, one of the earliest colonial settlements in the Amazon. The Iquitos-Nauta highway is one of the most expensive roads per kilometer on the planet.Combining ethnographic and historical research, Harvey and Knox shed light on the work of engineers and scientists, bureaucrats and construction company officials. They describe how local populations anticipated each of the road projects, even getting deeply involved in questions of exact routing as worries arose that the road would benefit some more than others. Connectivity was a key recurring theme as people imagined the prosperity that will come by being connected to other parts of the country and with other parts of the world. Sweeping in scope and conceptually ambitious, Roads tells a story of global flows of money, goods, and people—and of attempts to stabilize inherently unstable physical and social environments.

A renowned historian and engineer explores the past, present, and future of America's crumbling infrastructure. Acclaimed engineer and historian Henry Petroski explores our core infrastructure from both historical and contemporary perspectives, explaining how essential their maintenance is to America's economic health. Petroski reveals the genesis of the many parts of America's highway system--our interstate numbering system, the centerline that divides roads, and such taken-for-granted objects as guardrails, stop signs, and traffic lights--all crucial to our national and local infrastructure. A compelling work of history, The Road Taken is also an urgent clarion call aimed at American citizens, politicians, and anyone with a vested interest in our economic well-being. Physical infrastructure in the United States is crumbling, and Petroski reveals the complex and challenging interplay between government and industry inherent in major infrastructure improvement. The road we take in the next decade toward rebuilding our aging infrastructure will in large part determine our future national prosperity.
