Abstract
A method of milling asphalt is disclosed. The result of a survey of the unmilled asphalt pavement surface adjacent to the area to be milled is received. The result of the survey is stored in a computer memory. A map of the design surface specifying the design elevation of the milled surface over the area to be milled is stored in the computer memory. The relative elevation of the unmilled asphalt pavement surface adjacent to the area to be milled with respect to the machine body and rotatable milling drum of an asphalt milling machine is sensed. The elevation of the bottom surface of the rotatable milling drum is determined using a computer processor. The elevation of the milling machine body and the rotatable milling drum is automatically adjusted such that the milling drum mills the asphalt surface to the design elevation over the area to be milled.
