SUMMARY:Ohio LTAP: Winter Pothole Treatments for Local Roads (Virtual)
DESCRIPTION:Date: August 4\, 2026 \nTime: 10:00 – 11:00am PT \nThis research was conducted to identify efficient and cost-effective pothole patching treatments and provide recommendation for optimal methods and materials that various Local Public Agencies (LPAs) can use to enhance the performance and longevity of pothole patches installed during the winter season. To achieve these objectives\, a survey of LPAs in Ohio and nationally and a comprehensive literature review were performed to identify the best methods and materials used for winter pothole patching. A comprehensive field testing plan was developed to evaluate the identified methods and materials. The testing plan considered different factors pothole patching methods and/or materials combination\, pothole size and depth\, pavement structure type\, type of road and traffic\, and climate region and weather. A total of 686 patches were installed as part of the testing plan in different LPAs in Ohio using the considered method and materials and their combination. In addition\, the patches performance and longevity were monitored. Data mining techniques were employed in order to identify the factors that dictates the patch performance. In addition\, survival analysis was conducted to determine the expected lifetime of the different patching methods/materials combinations. Finally\, cost analysis was conducted to determine the life cycle cost of the different patching methods/materials combinations. This presentation will provide information on the findings and recommendations.
