Developing countries in the tropics often have challenging natural conditions and different institutional and financial institutions to industrialized countries. However, most textbooks on road engineering are based on experience in industrialized countries with temperate climates. Road Engineering for Development (published as Highway and Traffic Engineering in Developing Countries in its first edition) provides a comprehensive coverage of the planning, design, construction and maintenance of roads in developing and emerging countries. It covers a wide range of technical and non-technical problems that may confront road engineers working in the developing world. This new edition has extended the focus to include those countries of the former Eastern Bloc, which share many institutional issues and the financial problems confronting developing countries. Designed as a fundamental text for civil engineering students this book also offers a broad, practical view of the subject for practising engineers. It has been written with the assistance of a number of world-renowned specialist professional engineers with many years experience working in Africa, the Middle East, Asia and Central America.
