Abstract: A compaction roller particularly useful for vibration compaction of the shoulder area of roadways. The compactor is designed as an attachment for side-mounting to self-propelled or motorized machinery (e.g. a skid steer front loader). The compaction roller contains: (a) a front section comprising a frame connected to a front cylindrical roller; (b) a rear section comprising a frame connected to a rear cylindrical roller; (c) a joining means pivotally connecting said front and rear sections; and (d) a means for attaching to a self-propelled machinery in a side-mounted fashion. The pivoting compactor allows for simultaneous pinching and compacting on two different planes and reduces the hazards of operating a road roller compactor directly on a sloped surface.
