Current and Future Best Practices for Pothole Repair in Illinois

Abstract

This report presents a review of flexible pavement pothole-patching materials, equipment, and techniques within Illinois Department of Transportation as well as other transportation agencies in the United States. The research team conducted a literature review to examine recent studies and available state department of transportation guidance on pothole patching. Overall, this review revealed a lack of recent studies on this topic, and a greater need for them. The review also revealed that most states do not have centralized guidance for pothole repair best practices. The researchers also met with all nine Illinois Department of Transportation districts to determine their current state of practice for pothole patching. The meetings revealed a wide range of materials and techniques in use among the nine districts as well as areas where improvements can be made. The final chapter of this report includes overall recommendations for improvement.
