Abstract
Method of adjusting the height of a fixed rail carriageway, in which the sleepers supporting the rails are embedded in a carriageway panel resting on a substrate includes the steps of separating the carriageway panel from the substrate at the common contact face, forming filling apertures extending from the upper face to the lower face of the carriageway panel, lifting the carriageway panel to a fixed target height, incorporating a flowable casting material through the filling apertures in order to fill the space between the carriageway panel and the substrate, wherein separation is effected by pressure impacts.
