ABSTRACT:
An apparatus and method for compacting a material sample, such as soil or paving material, including a mold for receiving the material sample and a ram mounted for movement into a first open end of the mold to provide an axial compressire force thereto. The compacting apparatus also includes a base for supporting a second end of the mold. In operation, the mold is gyrated simultaneously with the application of the axial compressire force by the ram. Gyration is provided by tilting the mold from an initial neutral position in which the center longitudinal axis of the mold is collinear with the axis of compression to a tilted operative position in which the central longitudinal axis of the mold is angularly offset from the axis of compression. The base is thereinafter rotated relative to the mold so as to revolve the center of the second end of the mold about the axis of compression, thus, gyrating the axially compressed material sample. Such simultaneous gyration and axial compression simulates the rolling of a vehicle tire or other compaction device over a material surface.
