Pavement milling is achieved using a heavyduty piece of construction equipment known as a milling machine, or a cold planer. Milling machines utilize a large, rotating drum that removes and grinds the surface of the asphalt. Scrolls of tool holders cover the exterior of the drum and hold the carbide cutters that actually cut the pavement.
