Cubic Yards = (Length × Width × (Depth ÷ 12)) ÷ 27

Crusher run (Quarry Process / Item 4) contains crushed stone ranging from 3/4 inch down to microscopic stone dust. It weighs ~2,850 lbs per cubic yard and packs into an impermeable solid base.

Why Stone Dust Matters in Crusher Run

The stone dust acts as a natural binder. When watered and compacted, crusher run sets almost like concrete, preventing weeds and stopping pavers from shifting.
