What are the layers of material used to pave a parking area with asphalt concrete?

Paving a parking area with asphalt concrete typically involves several layers, including a subgrade layer, which is the natural soil compacted to provide a stable foundation. Above this, a subbase layer of granular material is often added for drainage and support. The base layer, made of crushed stone or gravel, provides additional strength, while the top layer consists of asphalt concrete, which is designed for durability and smoothness. Together, these layers ensure a well-structured and long-lasting parking surface.
