Innovative Pothole Repair Materials and Techniques

Potholes in asphalt pavement surface have detrimental effects on asphalt pavement deterioration and traffic safety. The cost-effective pothole repair methods are needed for highway agencies at all levels. This project aims to identify and evaluate innovative tools, technologies and materials for pothole repair in New Jersey. In phase I, the pothole repair methods that have potential to improve the cost-effectiveness of current practice at NJDOT will be identified and analyzed using life-cycle cost analysis. In phase II, the identified technologies and materials will be further studied through analytical modeling, laboratory testing, and field implementation. The optimized heating procedures will be developed considering heat source, pothole geometry, and weather condition. The effective test procedures and performance requirements on pothole repair materials to ensure good performance and bonding in the field will be studied and specified. Finally, the draft specification for pothole repair and the recommended material products will be developed for NJDOT.
