Highway Design and Construction


Book Description

This textbook for students on BTEC and degree courses in civil engineering covers highway pavement materials and pavement design and maintenance. The text has been updated to reflect current practice in highway engineering and UK specifications.




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.







Methodology of Highway Engineering Structural Design and Construction


Book Description

This book mainly studies the methodologies of structural design and construction for highway engineering, which are applicable to the overall control and the precise operation of engineering structures. It explores the method of comprehensive analysis, the simplification of complex problems, and the application of typical engineering tools. In turn, the book presents a number of innovative approaches, e.g. the coordinated control of structural deformation method, the theory of underground engineering balance and stability, and the soft soil foundation treatment of “bumping at the bridgehead.” These methodologies are then illustrated in typical cases and representative problems, explained from a practical standpoint. Examples in special settings are also discussed, e.g. highway construction in Tibet, and rebuilding after the Wenchuan earthquake. The book offers a valuable reference guide for all those whose work involves highway engineering design, construction, management, and scientific research.




Roadside Design Guide


Book Description

This document presents a synthesis of current information and operating practices related to roadside safety and is developed in metric units. The roadside is defined as that area beyond the traveled way (driving lanes) and the shoulder (if any) of the roadway itself. The focus of this guide is on safety treatments that minimize the likelihood of serious injuries when a driver runs off the road. This guide replaces the 1989 AASHTO "Roadside Design Guide."




Highway Construction and Inspection Fieldbook


Book Description

Maintaining complete, comprehensive, detailing records of every process or deliverable items is fundamentally essential to the efficient control of the work, to the achievement of all Company and Project objectives and to the management of the potential risks and opportunities that could be encountered during the prosecution of the work. Any company is taking a great risk if the Inspector, Supervisor or Leadsmen is unable to recognize that one of the greatest problems about the daily field report is that the information in them will not be needed if there is not a problem. However, when and if a problem arises the information logged on the Daily Field Report will be of great importance when dealing with the problem. This field book is a tested methodology that if used well and daily will provide consistent information to the user, but also to upper management. This field book aggregates procedures used by roadwork experts and it has been designed considering the fact that personnel on site is not always well versed on writing documents. This is a step by step collection of information that will document the minimum data required to create a useful construction daily report.




A Guide for Achieving Flexibility in Highway Design


Book Description

Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.




Concrete Pavement Design, Construction, and Performance


Book Description

Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.




Fundamentals of Road Design


Book Description

This reference book communicates the basic theoretical knowledge, the practical requirements and experience for designing, mapping, calculating and checking roads and the planning process overall and at the same time reveals important development trends. The book is guided by the current rules and regulations in Germany, it universalizes this knowledge and also integrates important current research results in road design processes. In order to restrict the scope of the book, it only deals with the theoretical principles and knowledge, and the practical experience for designing rural roads, i.e. the special features of urban roads are not mentioned here. This clear separation primarily results from the different principles and rules and regulations. The terms, definitions, abbreviations and formula symbols are based on German usage, but can be transferred to an international framework without any difficulties. The work is particularly designed to be a course book for students of road design. As a reference book, it supports the ongoing training process for road transportation engineers in planning offices and public bodies. Any specialist working in the transportation sector can use it as a reference book.
