The stability of the entire track and therefore the track geometry depends decisively on the load-bearing capacity of the formation protective layer (FPL). Problems arising in the foundation of the track increase the expenditure for track maintenance and shorten the service life of the track material. Enormous additional costs are the consequence.
Plasser & Theurer supplies extremely efficient machine systems for rehabilitation of line sections with substructure problems. These machines ride on the track and work in assembly-line mode to produce an optimum FPL. Using integrated ballast washing plants, crushing plants and mixers, large quantities of the old material can be reconditioned and used for the FPL, which saves considerable costs. Correct installation of geosynthetics helps to achieve an excellent initial quality of the track, thus substantially raising the quality reserve.
