Abstract (en)
[origin: EP0629744A2] For the subgrade-rehabilitation of a ballast bed (10) of a track (9), old ballast (6) of the ballast bed is continuously removed to clear a track formation (51), formation fine gravel (51) is released onto the cleared track formation and compacted to form a formation-protecting layer (43). Some of the old ballast (6) of the ballast bed is broken up in a stone crusher device (3) and released onto the cleared track formation (51) to form the formation-protecting layer (43). <IMAGE>
