This pothole repair experiment, conducted as part of the Strategic Highway Research Program (SHRP) H-106 project, is the most extensive attempt to date to improve the state of the practice for pothole repair operations. Pothole repair in asphalt concrete pavements is one of the most commonly performed maintenance operations for most agencies, especially in areas where cold winters and warm, wet springs contribute to accelerated pavement breakup every year. Potholes also hold the distinction of being the most aggravating pavement distress to the traveling public. For all the time and effort spend to prevent and repair potholes, the SHRP H-106 project was the first major effort undertaken to test cold-mix asphalt patching materials, those most commonly used for winter and springtime pothole repairs. The primary goal of this project was to identify those materials and techniques that are potentially the most cost-effective.
