What is micro surfacing?

Micro surfacing is a pavement maintenance technique that involves applying a mixture of polymer-modified asphalt emulsion, aggregate, mineral fillers, and water to an existing asphalt pavement surface. This process creates a new, thin protective layer that helps restore skid resistance, fill minor surface irregularities, and extend the life of the road. Micro surfacing is commonly used on highways, city streets, and airport runways because it cures quickly, minimizes traffic disruptions, and provides a cost-effective way to preserve pavement.
