Asphalt Aggregate Screenings

Asphalt aggregate screenings are the fine crushed stone sifted out during quarry production. The pieces run from about 3/8 inch down to stone dust. They're angular and well-graded, so the chips and dust pack tightly when you compact them. Most screenings come from the same limestone, granite, or trap rock quarries that supply stone to asphalt plants.

The word asphalt in the name only tells you where these screenings come from. They're the fine cut of rock that gets blended into hot asphalt mix at the plant, and any surplus gets sold on its own. You'll pay less per ton than for clean crushed stone because screenings are a byproduct. Some yards call the same stuff quarry screenings, stone dust, or 1/4-inch minus.
