Recycled Materials Asphalt Aggregate
Recycled asphalt is old road pavement that's been ground back down into gravel-sized pieces. When a road gets repaved, a milling machine scrapes off the top layer and crushes it. What you get looks like dark gray or black gravel, with a thin coating of old asphalt binder still on the rock. The pieces are angular, so they lock together under weight instead of rolling.
You'll hear it called RAP (reclaimed asphalt pavement), millings, grindings, or blacktop millings. It's usually cheaper than fresh crushed stone because the road that made it already got paid for once. In warm weather the leftover binder helps the pieces stick and pack down hard, which is why folks use it for driveways they don't want to pave.

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