Abstract
In a road construction machine () for the treatment of road surfaces with a milling drum () height-adjustable with regard to the milling depth, with a leveling device () with at least one controller () which receives set values for the milling depth and/or the slope of the milling drum (), and with at least one exchangeable sensor (A, B, C) or with several switchable sensors for registering the current actual value of the milling depth and/or the slope of the milling drum () relative to a reference surface, where the controller () effects a milling depth control and/or a slope control for the milling drum () conditional on pre-determined set values and the currently measured actual values of the at least one sensor (A, B, C) by returning an adjustment value for achieving or maintaining the set value during the milling operation, where the leveling device () is provided with an indication and setting device () for indicating and setting operating parameters for the at least one sensor (A, B, C), it is provided that the indication and setting device () of the leveling device (), in addition to an indication and setting unit () provided for the at least one sensor (A, C) currently in use, is provided with an additional indication and setting unit () for a selectable sensor (B) that is to be exchanged for the sensor (A, C) currently in use.
