Abstract (en)
[origin: EP2298993A2] The method involves forwardly moving a work-train on a track in a continuous work sequence. An old crushed stone layer is removed by a working unit (1). A new crushed stone layer is inserted by the working unit. An old base layer is removed by another working unit (2). A new base layer is inserted by the latter working unit, where the working units are separately drivable. The former working unit is provided with a mounting and processing device (6) for mounting and processing a crushed stone of a crushed stone layer.
