Abstract:Rehabilitation and maintenance of the 70,000-mile state highway system requires in excess of one-half billion dollars annually. Optimal use of these funds is a challenge to the highway engineer considering todays inflation, existing manpower limitations, material shortages and the present condition of the highway system. This report presents a set of brief guidelines which can be used by the field engineer to identify types of pavement failures (distress) and select suitable rehabilitation and maintenance alternatives. Companion reports provide information from which the field, laboratory, design and research engineers can perform detailed pavement distress investigations and select the most cost effective and energy efficient rehabilitation or maintenance alternative (1, 2, 3).
