Recycled Materials 57 Stone
Recycled #57 stone is old concrete that's been crushed and screened down to pieces between about 1 inch and 1/4 inch. The dust and fines are washed out, so what you get is clean, angular chunks that lock together under weight. Most of it comes from broken-up sidewalks, driveways, and building foundations that would've headed to a landfill.
The 57 is a screen size from the ASTM D448 spec. It's the same size range as regular #57 crushed stone, just made from recycled concrete instead of fresh quarry rock. You'll usually pay less per ton than virgin stone since the concrete's already been used once. It's a solid pick for driveway base, drainage under slabs, French drains, and pipe bedding.

What people use it for
How to choose within recycled materials 57 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.
