Potholes are a dangerous and costly nuisance, and the only way to keep them from coming back is to repair them effectively. However, long-lasting fixes aren’t easy.
This report identifies and describes current Canadian and international agency pothole repair best practices. It also recommends seasonal strategies for temporary and long-term patching, and for evaluating and selecting patching products that lead to improved performance of asphalt and chip seal roadways. Finally, it provides guidelines for evaluating new patching products, including laboratory and field testing.
Recommendations in the report address public communications; repair guidelines; performance measurement; prevention, maintenance and preservation; and training.
