Manual for Condition Rating of Gravel Surface Roads


Book Description

The existing pavement condition rating systems used in Ontario are designed only for hard surfaced roads. To date, there has been no system designed and developed specially to address the unique performance pattern of gravel surface roads. This document was prepared to meet this need and to present a roadway surface condition rating system for gravel surface roads. The manual covers the rating system, distress manifestations, procedures for roadway evaluation, surface defects, surface deformation, and shoulder distress manifestations.




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 is 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.

National Highway Functional Classification and Needs Study Manual (1970-1990).


Book Description

This manual has been prepared to guide Bureau of Public Roads field offices, the States, and local governments in preparing estimates of needs on consistently defined functional systems using uniform procedures. The objective of the study is to provide reliable data upon which consideration of future highway financing and responsibility can be based.







Rural Road Condition Survey Guide


Book Description

Developed to help provide a consistent means of assessing rural roadway conditions, both within a country and statewide. The roadway evaluation methodology described in this guide will provide county highway agencies with uniform and consistent means of defining pavement and roadway conditions. By adopting a standard approach to rating the observable condition of a pavement or gravel-surfaced road, local road agencies can uniformly and objectively compare pavement conditions. Illustrated.
