Aggregate Base Course (3.5″)

Aggregate Base Course in a 3.5” Size Range

Aggregate Base Course in a 3.5" size range is a foundational construction material composed of crushed stone or gravel. This material is typically produced by mechanically crushing larger rocks to achieve a consistent, coarse aggregate size. The 3.5" size range means the particles are relatively large, providing excellent load-bearing capacity and structural stability.




The larger aggregate size is ideal for heavy-duty applications where strength and drainage are critical. It is commonly used as a sub-base for roadways, highways, parking lots, and large commercial or industrial projects. In residential settings, it serves as a robust base layer for driveways, patios, and foundations. The coarse texture allows for superior drainage, reducing the risk of water pooling and frost heave. However, due to its size, this material is not suitable for areas requiring a smooth or compacted surface finish. Its primary advantage lies in its durability and ability to support substantial loads.
