asphalt overlay

Asphalt overlay is a road maintenance technique where a new layer of asphalt is applied over an existing pavement. This process helps to improve the surface's smoothness, extend the road's lifespan, and enhance safety by providing better traction. Overlaying is often used to repair cracks and potholes without the need for complete reconstruction, making it a cost-effective solution. It also adds structural support to the underlying layers. Overall, asphalt overlay helps ensure that roads remain safe and functional for vehicles while minimizing disruption to traffic.
