Abstract
An apparatus and method for milling rumble strips into a pavement surface with a cutting wheel. The cutting wheel has rows of a cutting and non-cutting surface and is rotated to alternately present and withdraw a cutting surface and a non-cutting surface to the asphalt and cut a periodic rumble strip pattern as the apparatus moves forward. This alternating pattern is achieved without any up and down motion of the cutting wheel, and the apparatus can be operated a relatively rapid speed.
