Abstract: An apparatus for compaction, breaking and rubbilization comprises a first non-circular plate having a first plate flat portion and a first plate thickness, a second non-circular plate having a second plate flat portion and a second plate thickness substantially equivalent to the first plate thickness, and a third plate having a third plate first flat portion and a third plate second flat portion and a third plate thickness less than the first plate thickness and the second plate thickness. The first plate flat portion is coupled to the third plate first flat portion and the second plate is coupled to the third plate second flat portion and each of the first plate, the second plate and the third plate are configured to form a multi-lobed roller assembly.

Abstract: A concrete rubblizing apparatus includes a non-circular multi-lobed roller connected to an axle on a wheeled frame such that the roller rolls upon the ground and the frame is towed by a tractor. Each lobe of the roller includes a set of cleats extending across a width of the roller and projecting outwardly from the impact surface of each lobe along a line parallel to the axle. The method of rubblizing includes moving the roller over a predetermined area of concrete along four, sequential overlapping paths.

Abstract: A compaction roller assembly includes a lobed non-circular impact roller operably mounted on a draw frame and a grader operably mounted behind the impact roller to level the corrugated ground surface produced by the impact roller. The grader includes a pair of diverging frame members with a pair of blades mounted thereon and depending therefrom with the lower edges of the blades lying within a generally horizontal plane. A plurality of teeth may be mounted to the frame members to scarify the soil, each tooth being removably connected to the frame members to permit ease of conversion between a grader blade and a scarifier. Each tooth is a generally flat plate, the plates oriented parallel to one another and parallel the line of travel of the grader. Each tooth plate forward edge includes a concave arc-shaped lower portion extending from the lower end of the tooth to a point proximal the lower edge of the blade.

Abstract: A concrete breaking apparatus includes a non-circular multi-lobed impact roller connected via an axle to a wheeled frame such that the roller rolls upon the ground as the frame is towed by a tractor. Each lobe of the roller includes a ridge extending across the width of the roller and projecting outwardly from the impact surface of each lobe along a line parallel to the axle and generally centrally located within the dynamic impact region of the impact surface. The ridge may take various configurations, including a triangular cross-section, a semi-circular cross-section, and a plurality of spaced apart projections.
