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.

Discover the twists and turns of one of America’s great infrastructure projects with this “engrossing history of the creation of the U.S. interstate system” (Los Angeles Times). It’s become a part of the landscape that we take for granted, the site of rumbling eighteen-wheelers and roadside rest stops, a familiar route for commuters and vacationing families. But during the twentieth century, the interstate highway system dramatically changed the face of our nation. These interconnected roads—over 47,000 miles of them—are man-made wonders, economic pipelines, agents of sprawl, uniquely American symbols of escape and freedom, and an unrivaled public works accomplishment. Though officially named after President Dwight D. Eisenhower, this network of roadways has origins that reach all the way back to the World War I era, and The Big Roads—“the first thorough history of the expressway system” (The Washington Post)—tells the full story of how they came to be. From the speed demon who inspired a primitive web of dirt auto trails to the largely forgotten technocrats who planned the system years before Ike reached the White House to the city dwellers who resisted the concrete juggernaut when it bore down on their neighborhoods, this book reveals both the massive scale of this government engineering project, and the individual lives that have been transformed by it. A fast-paced history filled with fascinating detours, “the book is a road geek’s treasure—and everyone who travels the highways ought to know these stories” (Kirkus Reviews).
In 1915, the road system in south Florida had changed little since before the Civil War. Travelling from Miami to Ft. Myers meant going through Orlando, 250 miles north of Miami. Within 15 years, three highways were dredged and blasted through the Everglades: Ingraham Highway from Homestead, 25 miles south of Miami, to Flamingo on the tip of the peninsula; Tamiami Trail from Miami to Tampa; and Conners Highway from West Palm Beach to Okeechobee City. In 1916, Florida's road commission spent $967. In 1928 it spent $6.8 million. Tamiami Trail, originally projected to cost $500,000, eventually required $11 million. These roads were made possible by the 1920s Florida land boom, the advent of gasoline and diesel-powered equipment to replace animal and steam-powered implements, and the creation of a highway funding system based on fuel taxes. This book tells the story of the finance and technology of the first modern highways in the South.
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.
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.
The steep rise in road mobility that has taken place during the last decades has resulted in some negative effects that are relevant from a social and economic point of view, such as accidents, congestion, and air pollution. Solutions to mitigate these effects have resulted in improvements in vehicles, infrastructure, and planning. Among these improvements are Intelligent Transport Systems (ITS), or digital road maps, which are based on electronics, control and telecommunications. This book discusses highway construction financing; the balanced vehicular traffic model that describes traffic flow on highways; non-drivers as road users; road engineering and public-private partnerships in highway and transit infrastructure building.
