Gyratory compactor apparatuses and associated methods

摘要

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.

主权项

1. An apparatus for compacting a construction material specimen, comprising;
a frame defining a chamber for receiving the specimen therein; a mechanical coupling that applies at least one of shear, compressive, kneading and rotational forces to the specimen; and a resilient mold defined within the chamber and enclosing a circumference of the specimen to impart a hoop compressive force to the specimen during compression thereof, the mold and the frame defining an expansion gap therebetween that allows for outward radial expansion of the mold and specimen contained therein.
