Abstract
An apparatus adapted to interact with a cylindrical mold for a gyratory compactor so as to determine a property of the gyratory compactor is provided, wherein the mold is adapted to contain a sample therein. Such an apparatus comprises a rigid disk-shaped plate defining an axis and a periphery, with the plate being adapted to be disposed within the mold. At least one sensing device is operably engaged with the plate, wherein the at least one sensing device is configured to measure a proximity of the at least one sensing device with respect to a reference member and to produce a corresponding signal indicative of the property of the gyratory compactor. In one embodiment, the apparatus is configured to determine the gyration angle of the mold, while in another embodiment, the apparatus is configured to determine the pressure exerted on the sample within the mold. The property of the mold may be determined either statically or dynamically. Associated apparatuses, devices, systems, and methods are also provided.
