Abstract: The present invention relates to a ground compaction apparatus for compacting a subsoil cover layer, with at least one compaction roller, a cover edge processing apparatus comprising an edge processing roller and having a cut material deflector, the cut material deflector being mounted on the cover edge processing apparatus with the aid of a mounting device, the mounting device being configured such that the relative position of the at least one material guide surface of the cut material deflector can be changed automatically with respect to the adjustable roller holding device of the cover edge processing apparatus. The present invention also relates to an asphalt roller having such a ground compaction apparatus and a method for operating such a ground compaction apparatus.
