Manual for Condition Rating of Surface-treated Pavements


Book Description

Rating of highway pavement surface condition is used by highway system authorities as a measure of the ability of the pavement to continue to provide required service to the public. Ratings are based on riding quality and distress manifestations which currently apply only to those roads surfaced with asphaltic concrete and Portland-cement concrete. There is also a network of bituminous surface-treated roads for smaller and more remote population centres which has, to date, had no scheme designed and developed specifically to address their performance pattern. This manual presents a pavement surface condition rating scheme for such roads, based on the same interrelated measures used on the highway system. The manual describes the scheme, and gives a procedure for evaluation, defines riding quality, and details such distress manifestations as surface defects and deformation and cracking, shoulder distress, and maintenance treatments.







Gravel 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.

Low-Volume Road Engineering


Book Description

"Everything that sustains us – grown, mined, or drilled – begins its journey to us on a low-volume road (Long)." Defined as roads with traffic volumes of no more than 400 vehicles per day, they have enormous impacts on economies, communication, and social interaction. Low-volume roads comprise, at one end of the spectrum, farm-to-market roads, roads in developing countries, northern roads, roads on aboriginal lands and parklands; and at the other end of the spectrum, heavy haul roads for mining, oil and gas, oil sands extraction, and forestry. Low-Volume Road Engineering: Design, Construction, and Maintenance gives an international perspective to the engineering design of low-volume roads and their construction and maintenance. It is a single reference drawing from the dispersed literature. It lays out the basic principles of each topic, from road location and geometric design, pavement design, slope stability and erosion control, through construction to maintenance, then refers the reader to more comprehensive treatment elsewhere. Wherever possible, comparisons are made between the standard specifications and practices existing in the US, Canada, the UK, South Africa, Australia and New Zealand. Topics covered include the following: Road classification, location, and geometric design Pavement concepts, materials, and thickness design Drainage, erosion and sediment control, and watercrossings Slope stability Geosynthetics Road construction, maintenance, and maintenance management Low-Volume Road Engineering: Design, Construction, and Maintenance i s a valuable reference for engineers, planners, designers and project managers in consulting firms, contracting firms and NGOs. It also is an essential reference in support of university courses on transportation engineering and planning, and on mining, oil and gas, and forestry infrastructure.




Guide for Pavement Friction


Book Description

This report contains guidelines and recommendations for managing and designing for friction on highway pavements. The contents of this report will be of interest to highway materials, construction, pavement management, safety, design, and research engineers, as well as others concerned with the friction and related surface characteristics of highway pavements.




Pothole Practices Guidebook: Proactive Prevention and Patching


Book Description

Even with best practices and standards, asphalt pavements will inevitably deteriorate due to traffic, environmental effects, and aging of materials. Preserving and extending their useful life requires a comprehensive preventive maintenance program and timely, effective, and efficient repairs. This easy-to-use guidebook provides an overview of how potholes form, pothole repair methods and materials, and preventive measures.
