Overall, from 2003 to 2011, locally available conventional cold mix was used with an average annual pothole count of 17,635 ranging from 14,369 to 24,061 potholes. From 2012 to 2013 UPM Permanent Pavement Repair Material was used. The average annual potholes count was reduced to 7,002, ranging from 5,972 to 8,032. Using UPM mix reduced pothole count by 10,633 (or 60%). The cost per pothole was determined to be $32 per pothole. Reducing the pothole count saved the city $340,256 per year. Reducing the number of potholes also improves worker safety.
