Book Description
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.

Book Description
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.

Book Description
Road asset management is one of the top priorities of the Central Asia Regional Economic Cooperation (CAREC) Transport and Trade Facilitation Strategy 2020. The implementation of performance-based road maintenance contracts (PBCs)—an essential element of road asset management—promotes effective and efficient maintenance of road networks. Well-designed PBCs keep roads in predefined good condition at relatively low cost. This guide aims to help policy makers in CAREC member countries understand and implement PBCs. After a brief history of the development of PBCs, it discusses the various types of PBCs and their relative advantages and disadvantages. It highlights PBC implementation in selected developed, developing, and transitional countries, including CAREC member countries, to illustrate best practices.
