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.
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.
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.
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."
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.
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.
Traffic, highway, and transportation design principles and practical applicationsThis comprehensive textbook clearly explains the many aspects of transportation systems planning, design, operation, and maintenance. Transportation Engineering: A Practical Approach to Highway Design, Traffic Analysis, and Systems Operations explores key topics, including geometric design for roadway alignment; traffic demand, flow, and control; and highway and intersection capacity. Emerging issues such as livable streets, automated vehicles, and smart cities are also discussed. You will get real-world case studies that highlight practical applications as well as valuable diagrams and tables that define transportation engineering terms and acronyms. Coverage includes:•An introduction to transportation engineering•Geometric design•Traffic flow theory•Traffic control•Capacity and level of service•Highway safety•Transportation demand•Transportation systems management and operations•Emerging topics
