A TEXTBOOK FOR STUDENTS enry BY JOHN H. BATEMAN, C.E. Member of American Society of Civil Engineers, Research NEW YORK JOHN WILEY & SONS, INC. COPYRIGHT, 1928 Printed in U. S. A. PRESS OF BRAUNWORTH & CO, INC. BROOKLYN, NEW YORK PREFACE THIS book is intended primarily for use as a textbook for students of Civil Engineering in an undergraduate course in highway engineering, and is based on the author's notes which he has used for several years in the teaching of highway engineering. The author has attempted to present the fundamental principles of the theory of highway engineering together with comprehensive descriptions of present practice. The treatment follows a definite plan in attempting to present the subject from the viewpoint of its principal divisions, namely, economics, financing, location, design, construction, maintenance and operation. The student should early understand that highway engineering is both a science and an art. Our present practice of highway engineering is based on the accumulated experience of many individuals and organizations; it owes much to extensive research investigations, particularly those of recent years. The author lays no claims to being a specialist in all of the branches of highway engineering, and therefore this book, in order to fulfill its purpose as a comprehensive text, represents a compilation of data, descriptions of practice, and opinions from many sources. Technical books, engineering journals and other publications have been freely consulted in its preparation. The author has endeavored to acknowledge the source of information so obtained at appropriate places in the text, and if any error has been made in this respect it has been done inadvertently.
