Aggregate Base Course (1″, Dust)

Aggregate Base Course with Dust in a 1” Size Range

Aggregate Base Course with dust in a 1" size range is a foundational construction material composed of crushed stone and fine particles. The inclusion of dust means the mix contains both larger aggregate pieces (up to 1" in diameter) and fine, powdery material. This blend is typically produced by mechanically crushing quarried rock, ensuring a consistent gradation of sizes.




The 1" size provides substantial load-bearing capacity, while the dust fills voids between larger stones, allowing for excellent compaction and stability. This makes it ideal for use as a sub-base for roads, driveways, parking lots, and patios, as well as under concrete slabs and pavers. The presence of dust helps lock the aggregate together, reducing movement and creating a firm, stable surface. However, the fine particles can generate dust during installation and may not be suitable for areas requiring high drainage. Overall, this material is valued for its strength, compaction properties, and versatility in both residential and commercial construction projects.
