Abstract (en)
[origin: EP2559812A2] The method involves developing a ballast of a ballast bedding (4) and removing material from a mixing zone (6) in a transition area between the ballast bedding and a base (5) together with a old ballast (4 ') of the ballast bedding. A mechanical enhanced base layer (8), a subgrade level protecting layer (9) and/or an anti-frost layer are incorporated with treatment material and/or external material of mixed development material. A supplementary interlayer is formed between the mechanical enhanced base layer, the subgrade level protecting layer and/or the anti-frost layer. An independent claim is also included for a device for enhancing or repairing railway tracks.
