3. It's a quick and cheaper way of surfacing a road

Thick tar is applied to the road. Often they don't even fill potholes. Then a layer of small stone chips are dropped on the tar. It begins to harden in about 2 hours. Sometimes they vacuum up stone that doesn't adhere. It leaves a rough surface. No steam rollers.
