Description: The Ser vopac is a fully automated,servo-controlled gyrator y compactor designed to compact asphalt mixes using the gyrator y compaction technique. Compaction is achieved by the simultaneous action of static compression and the shearing action resulting from the mould being gyrated through an angle about its longitudinal axis. The Ser vopac has a four column frame for superior rigidity.Ver tical stress is measured by a load cell and is accurately controlled during compaction.The gyrator y motion is also ser vo-controlled enabling the gyrator y angle to be accurately controlled during compaction,irrespective of load and any compliance of the machine ’s components.The Ser vopac does not require any wearing plate. The Servo-controlled operation of the machine allows vertical stress,gyrator y angle and speed to be quickly modified from a hand-held control pendant or PC .The shear stress facility is built into the Ser vopac and shear stress is measured/displayed on the PC screen. The PC-Windows (TM)interface provides a screen to input test parameters and display and plot either height,density,shear stress or angle against gyrator y cycles in real time. The test data may be stored and retrieved or transferred to other analysis packages. The Servopac is designed to comply with SHRP Superpave asphalt mix design requirements and the proposed CEN European Specifications on gyrator y compaction.
