The invention concerns a method for correcting height defects (y-), which consists in lifting a track by superelevation (y+), above a final ideal position (X) and tamping same, thereby enabling a temporary ideal position (X) to be obtained. Then with a view to stabilizing the track, the ballast bed of the track (2) is subjected to a different compaction to obtain finally, the desired ideal position (X). It is thus possible to prevent the track from returning to the previous defective position. |
