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.

Methods, compositions and systems for prolonging the lives of transportation surfaces, including pavement, runways, bridges and parking structures include physically altering the transportation surface and chemically protecting the transportation surfaces. Physical alteration of a transportation surface may include physically altering one or both of a microtexture and a macrotexture of the transportation surface. Chemical protection of a transportation surface may include hardening and/or densifying the transportation surface. The transportation surface may be chemically protected while physically altering the transportation surface or after the transportation surface has been physically altered.

A ground compactor for compacting ground material (10), comprising at least one compactor roller (22) rotatable on a machine frame about a roller rotation axis (W) substantially orthogonal to a longitudinal direction (L) of the compactor and a vertical direction (H) of the compactor and extending substantially in a transverse direction (Q) of the compactor, with an edge processing device (24) associated therewith for processing a side edge (38) of compacted ground material (10), wherein the edge processing device (24) comprises an edge processing disk (26) rotatably supported on a disk carrier (30) about an edge processing rotation axis (K), characterized in that the edge processing rotation axis (K) is set or can be set at a first angle of incidence (W1) with respect to the transverse direction (Q) of the compactor in the longitudinal direction (L) of the compactor.
