Highway Engineering 
Planning, Design, and Operations

The purpose of this handbook is to provide a reference book of principles, processes and data for those interested in the application of technology to highway transportation. In this book each section includes a discussion of applicable principles, relevant data, and formulas and examples where appropriate. Example solutions are incorporated for the typical problems. References to detailed theory and data are also provided. The sections are in Adependent so as to permit the reader to develop an understanding of the subject matter and a rudimentary knowledge of applications without excessive referencing to other sec Ations or sources.To present fundamental concepts and data for each phase of a subject as broad as high Away engineering required extreme conciseness in treating each subject. In addition to standard topics, such as planning, geometric design, soils and materials, new sections con Acerned with policy, management, quality, and environmental factors have been added.Throughout the handbook, the nature of the changes that are taking place is revealed, with emphasis on principles the reader will be able to understand and use. In summary, this handbook is designed to provide a simple, comprehensive, practical view of current Highway Engineering Handbook technology. Hopefully, it also provides a basis for understanding many of the trends and developments that the future holds.
