Most of these countries, which do not include the former Eastern Bloc countries, are situated in the tropics, where the natural conditions are different from related conditions in temperate regions. Also, the institutional issues and the financial problems confronting countries in the ‘South’ are usually different from the state of affairs in the ‘North’. However, most existing textbooks on highway engineering are geographically biased and based on experience from industrialized countries with temperate climates, or they deal with specific problems, for instance, soil stabilization or road building in the tropics. The aim of this book is to give a comprehensive account of the wide range of both technical and non-technical problems that may confront road engineers working in the Third World without giving a detailed coverage of methods and techniques. The book is designed primarily as a fundamental text for civil engineering students, but an additional objective is to offer a broader view of the subject for practising engineers. The book does not purport to address the safety problems associated with testing of road materials and construction and maintenance of roads. Readers are expected to establish appropriate safety and health practices and determine applicability of national regulatory limitations prior to use of any method described in the book. The text has been written with the assistance of a number of professionals with many years of experience gained in Africa, the Middle East, Asia and Central America. The names of the writers of the different chapters appear in the list of contributors, in the table of contents and under the headings of the chapters. I am indebted to them all for their contributions. My thanks also go to Wendy Taylor who helped with the preparation of Chapter 24; to Poul Harboe and Per Kirkemann who wrote background material for Chapter 25; to Arne Poulsen and Robin MacDonald who scrutinized various chapters; to Dr. Richard Robinson who assisted with manuscript review, and to Sanne Knudsen who did the proofreading.

  • Flexibility in Highway Design
    Flexibility in Highway Design U.S. Department of Transportation Federal Highway Administration Page i This page intentionally left blank. Page ii A Message from the Administrator Dear Colleague: One of the greatest challenges the highway community faces is providing safe, efficient transportation service that conserves, and even enhances the environmental, scenic, historic, and community resources that are so vital to our way of life. This guide will help you meet that challenge. The Federal Highway Administration (FHWA) has been pleased to work with the American Association of State Highway and Transportation Officials and other interested groups, including the Bicycle Federation of America, the National Trust for Historic Preservation, and Scenic America, to develop this publication. It identifies and explains the opportunities, flexibilities, and constraints facing designers and design teams responsible for the development of transportation facilities. This guide does not attempt to create new standards. Rather, the guide builds on the flexibility in current laws and regulations to explore opportunities to use flexible design as a tool to help sustain important community interests without compromising safety. To do so, this guide stresses the need to identify and discuss those flexibilities and to continue breaking down barriers that sometimes make it difficult for highway designers to be aware of local concerns of interested organizations and citizens. The partnership formed to develop this guidance grew out of the design-related provisions of the Intermodal Surface Transportation Efficiency Act of 1991 and the National Highway System Designation Act of 1995. Congress provided dramatic new flexibilities in funding, stressed the importance of preserving historic and scenic values, and provided for enhancing communities through transportation improvements.
