Aggregate Base Course (1.5″ Minus)

Aggregate Base Course in a 1.5” Minus Size Range

Aggregate Base Course in a 1.5" minus size range is a foundational construction material composed of crushed stone, gravel, or recycled concrete, with particles ranging from 1.5 inches down to fine dust. The "minus" designation means the mix includes both larger aggregate and smaller fines, which fill voids and help the material compact tightly.




This specific size range is ideal for creating a stable, load-bearing base layer beneath roads, driveways, parking lots, and concrete slabs. The blend of coarse and fine particles ensures excellent compaction and load distribution, reducing the risk of settling or shifting over time. While the fines improve stability, they can also reduce drainage compared to more open-graded materials. Overall, 1.5" minus Aggregate Base Course is valued for its strength, versatility, and reliable performance in both residential and commercial construction projects.
