  • Patent number: 9234824
    Abstract: A gyratory compactor apparatus is provided that is adapted to interact with a mold that defines a mold axis. The gyratory compactor apparatus includes a frame that defines a frame axis and has a first mounting plate and a spaced-apart second mounting plate. A pivoted support is carried by the frame and capable of rotation in at least a first and a second rotational degree of freedom. A mold-engaging device is carried by the pivoted support and has a first carriage plate proximal the pivoted support and a second carriage plate axially spaced-apart from the pivoted support for receiving the mold therebetween. At least one actuator having a first end is carried by the frame and a second end is carried by the second carriage plate for imparting lateral translation to the second carriage plate relative to the frame axis. An associated method is also provided.

  • Patent number: 9128012
    Abstract: A gyratory compactor apparatus adapted to interact with a mold that defines a mold axis is provided. The gyratory compactor apparatus includes a frame defining a frame axis, a pivoted support carried by the frame, and a mold-engaging device carried by the pivoted support and having a carriage plate spaced-apart from the pivoted support for receiving the mold. The carriage plate is movable relative to the frame axis by rotation of the pivoted support. At least one actuator is in engagement with the carriage plate for imparting translation to the carriage plate relative to the frame axis.

  • Patent number: 8082801
    Abstract: A gyratory compactor apparatus adapted to interact with a mold that defines a mold axis is provided. The gyratory compactor apparatus includes a frame defining a frame axis and having a first mounting plate and a pivoted support carried by the frame and capable of rotation in at least a first and a second rotational degree of freedom. A mold-engaging device is carried by the pivoted support and includes a first carriage plate proximal the pivoted support and a spaced-apart second carriage plate that defines a space therebetween for receiving the mold. The second carriage plate has at least one clamping rod in communication with an actuator for translating the second carriage plate about the mold axis to thereby secure the mold in the space between the first and second carriage plates. An associated method is also provided.

  • Publication number: 20050011276
    Abstract: A device for simulating the various forces a load of hot asphalt mix places on the inside of a gyratory compactor allows the calibration of the compactor without requiring actual asphalt to be used. Obviating the need for asphalt during calibration significantly increases the accuracy of the calibration and provides an opportunity for more data to be obtained. The device is capable of being heated to hot asphalt temperatures for more accurate calibration.
