Abstract
In a self-propelled construction machine comprising a working device (e.g. milling drum) and a profile sensor device arranged in front of the milling drum as seen in the direction of travel, the following features are achieved: the profile sensor device measures ground pavement profile data in at least one first location, wherein at least one second sensor device is provided which, after the construction machine has traversed a section corresponding to the distance between the milling drum and the profile sensor device, measures, in the first location, at least one distance value between the ground surface and the milling drum, wherein ground pavement profile data measured in the at least one first location is referenced to the at least one distance value measured in the first location by means of the second sensor device.
