Highway Engineering

This book is designed primarily as a text for junior, senior and fifth-year college courses in highway and transportation engineering. It is also a starting point for advanced courses and individual study in these areas. Furthermore, it summa¬rizes the state of the art and important new developments in transportation plan¬ning and highway technology to assist practicing engineers, administrators, and other decision makers. This book can, in the main, be used by those who have very little background in technical engineering. However, some knowledge of route surveying, dy¬namics, and fluid mechanics is necessary for a complete understanding of cer¬tain topics. These topics are included because they are important to more ad¬vanced students and to practicing engineers.For those who desire more detailed knowledge on specific topics, a substan¬tial number of pertinent references have been cited. They include classics from the past and others giving recent findings.
