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 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.
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.
Provides an analysis of rural road maintenance in the Asian region.
This is a useful guide to all facets of asphalt technology as applied to the construction and maintenance of highways and reflects the very best of UK asphalt and pavement technology. It covers all aspects of fully flexible road construction from foundation design through to surface treatment. The book also covers new materials.
