Jarring potholes can damage vehicles, delay traffic, and frustrate drivers. But that’s not all. Pothole repair is also one of the most expensive pavement maintenance activities. It’s estimated that agencies spend more than $1 billion in the United States each year on pothole and spall repair.
Maximizing knowledge from research and current practices for pavement patching helps agencies make the most of their funding and increase public satisfaction. To advance improvements, the Transportation Research Board recently published a National Cooperative Highway Research Program (NCHRP) Synthesis on Pavement Patching Practices. The synthesis report also is the basis for a new TERRA fact sheet about current practices for pothole patching.
The synthesis, which summarizes current practices for patching both concrete and asphalt pavements, takes a closer look at current state-of-the-practice for small-scale pavement defects or distresses. It examines current programs for repairing and patching; pavement distress factors; and repair and patching materials, design, and construction processes, among other topics.
