Aggregate Base is a construction material made from a mixture of crushed stone, gravel, and sand. It serves as a foundational layer for roads, parking lots, and other structures, providing stability and support. The material is compacted to create a solid base that can withstand heavy loads and resist shifting over time. This material is often used in civil engineering projects due to its durability and cost-effectiveness. Proper installation of Aggregate Base is crucial, as it helps prevent issues like settling and cracking in the surfaces built on top, ensuring long-lasting performance.
