Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 330: Public Benefits of Highway System Preservation and Maintenance examines the current practices for identifying, measuring, and articulating the public benefits of highway system maintenance and operation, and of communicating those benefits that are understandable and meaningful to stakeholders--road users, elected officials, and others who have an interest in the system's performance.

Book Description
Pursuant to a congressional request, GAO examined: (1) the condition of the Interstate Highway System; and (2) federal and state efforts to ensure its preservation. GAO found that: (1) the Federal Highway Administration (FHwA) noted that over 40 percent of all interstate pavement was rated in fair or poor condition; (2) interstate conditions are not expected to improve beyond 1989 levels because future interstate investment needs significantly exceed funding levels, interstate capacity-enhancement needs will increasingly compete with preservation needs, and the Department of Transportation (DOT) has no goals for minimally acceptable interstate pavement conditions; (3) adequate and timely preventive maintenance could delay costly pavement reconstruction; (4) highways in four of the seven states GAO reviewed had significant maintenance backlogs that could adversely affect the structural integrity of roadways and bridges and the safety of the motoring public; (5) FHwA has not developed measurable criteria or standards for assessing the adequacy of state maintenance and weaknesses in the FHwA inspection process further weakened its oversight of state maintenance efforts; and (6) the Interstate Resurfacing, Restoration, Rehabilitation, and Reconstruction (4R) Program could affect how states prioritize highway projects by funding such capital-intensive preservation activities as resurfacing and reconstruction at a 90-percent federal matching share and by not funding preventive maintenance.

Book Description
"Presents guidance for communicating the value of highway system maintenance and preservation. The report includes numerous examples and models that transportation agency staff members can use to present to agency leadership, elected officials, and the public to make the case for allocating budgetary and other resources to preserve and maintain the public's investment in highway infrastructure."--Publisher's description.

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
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.
