INTRODUCTION

When highway departments were first formed in the early 20th
century, they were seen as construction organizations. Design was a
minor responsibility of the organizations. Agency leadership
quickly realized, however, that constructing a road properly
required a technically adequate and implementable design. As a
fledgling road network developed, network maintenance became a
recognized activity im portant to the long-term success and
stability of the highway system. During World War II, very little
investment was made in the highway system, enabling the United
States to devote its resources to the war effort. After World War
II, the deteriorated highway system was rapidly expanded and
rehabilitated. This increased level of investment to expand and
rebuild the highway network created an awareness of the need to
begin a rational management process of highway maintenance.
