Explain about surface treatment using asphalt concrete. In English language

Surface treatment using asphalt concrete (also known as asphalt overlay or paving) is a process of applying a new layer of asphalt concrete over an existing road surface. The primary goal is to improve or restore the performance and appearance of the pavement.

This is done for several reasons:

• Restoration: It covers minor cracks, potholes, and other damage, preventing water infiltration that could further degrade the road's base layers.
• Improvement: It can enhance the smoothness of the surface, reduce tire noise, and improve skid resistance for vehicles.
• Protection: It shields the underlying pavement layers from environmental elements like sun, rain, and frost.
• Aesthetics: It provides a fresh, uniform look to the road.

The process typically involves cleaning the old surface, repairing any significant damage, and then laying and compacting the new asphalt concrete using specialized machinery.
