GRC-20 Servo Controlled Superpave Gyratory Compactor
The GCTS Gyratory Compactor offers a high level of accuracy while maintaining ease of use. The GRC-20 is a fully automated servo-controlled compactor that provides a high productivity rate.
The servo controlled mechanism provides a high level of accuracy for the tilt angle as well as the gyration rate and start/stop position. The servo actuators are isolated from the compaction area preventing any possible jamming from material spills. All of the compaction parameters are microprocessor-controlled. This allows user modifications of any parameter through simple on-screen controls without any cumbersome mechanical adjustment.
By introducing a self-heating mold with precise temperature control, the GRC-20 compactor eliminates the need to keep and handle multiple pre-heated molds providing an efficient and safe operating environment. The self-heating molds eliminate the handling of heavy and hot components for each compacted specimen. The mold temperature is precisely controlled allowing the user to specify the temperature during compaction. The controlled temperature can be prescribed to be constant or variable as a function of time during compaction.
