Oil Mat
Oil mat is a driveway or road surface built by spraying hot liquid asphalt on a packed base, then rolling small stone chips into the wet oil. The chips lock into the asphalt as it cools, leaving a hard, sealed top layer. It's the surface you see on a lot of rural roads and long country driveways. Once it cures, water sheds off and the loose chips get swept away.
You'll hear the same thing called chip seal, tar and chip, or oil and chip, depending on where you live. The chip is usually 3/8-inch crushed stone, like #8 or #89 rock, and the oil is an asphalt emulsion sprayed by a distributor truck. Oil mat costs less per square foot than paved asphalt and holds up better than plain gravel, so it's a middle-ground pick when you've got a long driveway or a private road to cover.
What people use it for
How to choose within oil mat
Ask before you order
These aren't catalog items. Confirm size, color, and delivery window with the yard before you commit — every load runs differently.
Match the job to the stone
Flagstone, boulders, ballast, glass gravel — each has one right job. Get the job clear first, then the stone follows.
Lead time is longer
A specialty order usually ships slower than a #57 pallet. Plan the delivery date around the material, not the other way around.
