Abstract:
1. A method for calibrating a gyratory compactor apparatus configured to compact and impart a displacement to a sample in a mold that defines a mold axis, the gyratory compactor apparatus including at least one actuator for imparting displacement of the mold relative to a longitudinal axis of the gyratory compactor apparatus, the method comprising the steps of: inserting a moment simulation device in a mold to apply a moment; imparting displacement of the mold relative to the gyratory compactor apparatus by actuation of the at least one actuator to thereby define a gyratory angle between the gyratory compactor apparatus and the mold axis; measuring the actual moment; applying a compression force onto the mold to thereby generate an actual moment; measuring at least one force applied by the at least one actuator; and determining a relationship between the measured at least one force applied by the at least one actuator and the applied moment.
