The appearance of asphalt always diminishes over time. Without ongoing maintenance, cracks and holes may form. This undermines the substrate and the most effective repair is to remove and replace the defective area. Resurfacing is used in the most severe cases. It is the most long term and cost effective way to ensure the safety and quality of the asphalt surface. The procedure includes removing the old asphalt by leveling, milling, and adjusting of drainage structures. Every project is unique depending on the location, quality, and other site-specific factors.
