The instrument is in accord with requirements of SUPERPAVE specification of FHWA. Its compaction degree meets requirements of AASHTO R35 and AASHTO PP35-98. It is an instrument to simulate actual road material volume and property. It is a shaping machine to make cylindrical test sample of hot-mix bituminous mixture by kneading methods under a constant pressure, at a fixed compaction angle, and a fixed compaction speed.
