Cold Patch
Cold patch is bagged asphalt you can shovel into a pothole without a hot mix truck. It's small crushed stone mixed with a binder that stays workable at room temperature, so you dump it in the hole, tamp it down, and drive on it the same day. The binder is either bitumen thinned with a solvent or bitumen emulsified in water. It hardens over time as the carrier evaporates and traffic packs the mix.
The "cold" in cold patch refers to the temperature you apply it at, not the size or spec. You can shovel it into a hole in freezing weather, where hot mix asphalt would set up before you got it in the ground. Cold patch usually shows up as a 50 lb bag at the hardware store, or by the ton for bigger jobs. It costs more per ton than plain crushed rock because the binder is doing the work of holding the patch together.
What people use it for
How to choose within cold patch
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.
