Screenings (#4, Dust)

Screenings with Dust in a #4 Size Range

Screenings with dust in a #4 size range are finely crushed stone byproducts, typically produced during the crushing and screening of larger aggregates. The #4 size range means particles are small-generally passing through a 4.75 mm (No. 4) sieve-while the presence of dust gives the material a powdery texture.




This fine, dust-laden aggregate is ideal for applications where a smooth, compactable base is required. The dust content helps screenings bind together, making them excellent for setting pavers, creating walkways, or as a leveling layer beneath patios and flagstone. In commercial settings, screenings are often used as a bedding material for pipes or as a base for asphalt. The main advantage of this material is its ability to compact tightly, reducing voids and providing a stable surface. However, the high dust content can make it less suitable for drainage applications and may create dust during installation.
