Abstract: A gyratory compactor apparatus is provided for interacting with a sample within a generally cylindrical mold having a flange. Such an apparatus comprises a frame defining an axis and an offsetable member engaged with the frame for engaging one end of the mold. The offsetable member is displaceable from the axis and is concurrently movable in an orbital motion thereabout. A pressure ram is movable along the axis and a mold-engaging device is engaged with the frame for receiving the mold such that the mold and frame axes are coaxial. The pressure ram is axially movable within the mold to apply a compaction pressure on the sample, and thereby maintains a portion of the mold at a gyration point along the frame axis. The mold-engaging device axially moves the mold into engagement with the offsetable member.

Abstract: 4 An apparatus adapted to extrude a sample from a mold for a gyratory compactor is provided, the mold defining an interior portion and opposed open ends. A platform sealingly engages one of the opposed ends of the mold and defines a port extending to the interior portion of the mold when the mold is engaged therewith. A piston member is disposed in the interior of the mold between the sample and the platform, and is also movable with respect to the interior of the mold while forming a pressure seal therewith. A pressure source is operably engaged with the inlet port and is configured to exert a pressure through the inlet port and against the piston member so as to extrude the piston member and the sample from the mold through the other of the opposed ends of the mold. An associated system and method are also provided.
