Asphalt milling usually occurs prior to installing a new asphalt layer or overlay and can be repeated on the same surface many times. It is also sometimes called cold planing, cold milling or profiling. The milling process entails a milling machine breaking up, crushing, and removing an entire pavement layer/s ranging from just the surface to milling down to the base. We will highly recommend replacement if your asphalt driveway or parking lot is beyond repair. While resurfacing may be less expensive in the short-term, eventually there will reach a point where the cost of repairs exceeds the cost of new asphalt installation
