Abstract (en)
[origin: EP0796950A1] The method involves milling a concentric slot around the frame on the outside, which extends in depth to at least the lower frame edge. The frame is lifted out by a lifting device (5), a new frame is fitted, and the slot is filled with a casting compound. The lifting device engages positively on the inside of the frame (7). The milling tool and lifting device are height-adjustably fastened in a frame (1), which supports itself on the asphalt road surface. A container (12) for cooling fluid is fastened to the frame.
