Renewal method and blast beds Track treatment train for its realization.

摘要

A renewal method bed ballast, wherein the ballast bed of a track is extracted, the ballast removed waste is reconditioned and the roadbed is recompose using ballast reconditioning waste resulting from the treatment of the ballast extracted waste, where the treatment of ballast removed waste is characterized by: - ​​subjecting the ballast waste at least one fractionation treatment, by which is obtained the ballast waste at least a fraction of ballast of a size range grain smaller grain sizes and at least a fraction of the range of ballast grain size of larger grain sizes in a given separation of at least one residue fraction case; - subjecting the fraction of ballast interval grain size of larger grain sizes to at least one treatment crusher designed to return to produce a state of ballast sharp edges, at a given separation of a residue fraction case; - grouping fraction ballast interval grain size of larger grain sizes subjected to treatment with crusher and fraction ballast interval grain size of smaller grain size not subjected to any treatment crusher in at least a fraction of ballast size range of smaller grain and larger grain sizes; and - preparing the combined ballast of grain size range of smaller and larger grain sizes as reconditioning ballast waste fraction.
