Dust (#10)

#10 Dust Aggregate

#10 dust aggregate is a finely crushed stone material, typically produced as a byproduct during the screening of larger aggregates. Its powdery texture and small particle size make it ideal for applications where a smooth, compactable base is required.

The #10 size range refers to particles that pass through a #10 sieve, resulting in a material that is finer than sand but coarser than silt. This fine gradation allows #10 dust to fill voids between larger aggregates, enhancing compaction and stability. It is commonly used as a setting bed for pavers, flagstone, and bricks, as well as a top layer for pathways and playgrounds. In commercial settings, it serves as a leveling agent beneath concrete slabs and asphalt.

Pros of #10 dust include excellent compaction, minimal shifting, and a smooth finish. However, its fine texture can lead to dustiness when dry and may require moisture control during installation. Overall, #10 dust aggregate is a versatile choice for both residential and commercial projects needing a stable, even surface.
