Abstract: A pressure verification device is provided which is configured to be used with a Superpave gyratory compactor to measure the pressure applied to a specimen of asphalt paving mix during the compaction process. The pressure verification device is positionable within the cylindrical mold of the gyratory compactor for dynamically measuring the pressure exerted upon the sample within the mold. The pressure verification device comprises a rigid disk-shaped plate having opposing surfaces, with at least one pressure transducer being carried by the disk-shaped plate on one of the opposing surfaces.

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. A securing device engaged with the offsetable member and movable therewith reversibly engages the mold to secure the mold to the offsetable member as the secured end is moved in the orbital motion by the offsetable member. The mold is thereby gyrated and dynamically maintained at a gyration angle. Associated apparatuses, devices, and methods are also provided.
