ABSTRACT:
A gyratory compacting apparatus and data capture and display system for compacting a specimen of material within a mold as the mold is gyrated, and capturing and displaying data on an internal angle of gyration during mold gyration, the apparatus and system having a generally cylindrical mold for holding a specimen of material to be compacted, at least one plate in the mold in contact with material in the mold and which moves relative to the mold as the mold is gyrated, and at least one sensor which measures an internal angle of gyration between the mold and a mold plate and captures internal gyration angle data for real-time display of internal gyration angle data during gyration and compaction. Alternative arrays of internal gyration angle sensors are disclosed.
