Abstract: In a method for stabilizing an earth formation exposed after removal of a track and ballast, in a first working pass in a work section following a rear crawler track with regard to a working direction, parallel to the removal of the ballast the earth formation is loosened up, aggregates are introduced, and grading takes place. In a second working pass, the earth formation to which aggregates have been added is mixed thoroughly by getting picked up by means of a clearing chain and transported onward to a discharge point located behind the rear crawler track and discharged again upon the exposed earth formation, after which, by grading and consolidating the discharged earth formation, a rehabilitation layer is formed.
