Book Description
The Superpave gyratory compactor (SGC) is used to compact asphalt specimens for mixture testing in the Superpave system. Five companies currently manufacture SGCs for use in the United States, offering a total of eight different models. Each model employs a unique method of setting, inducing, and maintaining the specified angle of gyration. Calibration systems are required for each device for the angle of gyration. All angle measurements are made externally relative to the mold and none of the calibration systems can be universally used on all of the models.

Book Description
There is evidence that some Kansas mixes, which have performed well in the past, will not meet the currently proposed design requirements for a Superpave level I mix. The major problem is low voids in the mineral aggregate (VMA). The major reasons for low VMA are the high amounts of natural sand currently used and the higher compactive effort required by Superpave compared to 50-blow Marshall compaction. Cores, plant produced (field) mix, the original aggregates and asphalt cement were obtained from four low volume pavements. The cores established the in-place density of the pavements. The field mix was compacted in the Superpave Gyratory Compactor (SGC) to establish the number of gyrations required to reach the field density of the mix. The aggregates and asphalt cement were obtained and Superpave mix designs were performed. The void properties were evaluated at the original and revised Ndesign gyrations. The effect of reducing the ram pressure from 600 kPa to 400 kPa was evaluated as well.
