Cost-Effective Pavement Repair Materialsby David G. Peshkin, ERES Consultants, Inc, Savoy, United States,
Abstract: In 1990, as part of the Strategic Highway Research Program's (SHRP) initiative in the highway operations area, a 2 1/2 -year research effort was initiated to study the cost-effectiveness of materials, equipment, and procedures used to perform several routine pavement maintenance activities. The maintenance activities included pothole repair in asphalt concrete (AC) pavements, crack sealing/filling in AC pavements, joint resealing in portland cement concrete (PCC) pavements, and partial-depth spall repair in PCC pavements. Under this project, test sites for each of the four maintenance activities were located and installed on highways across the United States and Canada. Installation and performance data have been compiled and analyzed to provide preliminary indications about distress development and survival rates of the various repairs. This paper presents an overview of the findings from the study performed in the four maintenance areas. While performance evaluations will continue for several more years (over 70 percent of the pothole repairs and 90 percent of the other repairs are still in service), some preliminary results are available and are presented. However, it must be emphasized that long-term performance can not be gauged until these repairs have been in place for much longer.
