Recycled Materials 1 Stone

#1 recycled stone is crushed old concrete screened to a large size, roughly 1½ to 3½ inches across. The pieces are chunky and angular, with the rubble washed clean of dust so water moves through fast. You'll spot bits of exposed rock and old cement paste baked into every chunk, because the source is broken-up sidewalks, foundations, and demo slabs.

The 1 comes from ASTM D448, the spec that sorts crushed stone by screen size. #1 is the biggest grade on that chart, so any rock or recycled concrete that matches the gradation gets the label. Recycled #1 runs cheaper than natural crushed stone because the raw feed is demo concrete instead of quarried rock, and it usually delivers within a few dollars a ton of quarry #1.

How to choose within recycled materials 1 stone

Base under something else

Reclaimed concrete or asphalt millings work great as base under a driveway or slab. The layer above hides what's underneath.

When the top layer is visible

Recycled base compacts to grey or dusty tan, not the clean look of fresh crushed stone. Fine under a surface course, off if it's the finish.

Check the source

Reclaimed loads vary by demo site. A supplier who can tell you where the feedstock came from is a better bet than the cheapest yard in town.
