Abstract:
1. A method of milling asphalt at a design height with an asphalt milling machine, said asphalt milling machine having a milling machine body, a rotatable milling drum mounted on the lower portion of said milling machine body, said bottom surface of said milling drum contacting said asphalt pavement surface, comprising receiving the result of a survey of the unmilled asphalt pavement surface adjacent to the area to be milled, storing the result of such survey in a computer memory, storing in the computer memory a map of the design surface specifying the design elevation of the milled surface over the area to be milled, sensing 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, determining the elevation of the bottom surface of the rotatable milling drum using a computer processor, and automatically adjusting the elevation of the milling machine body and the rotatable milling drum such that the milling drum mills the asphalt surface to the design elevation over the area to be milled.
