Specifications include, but are not limited to: In addition to HMA, a SGC with a capability to compact other materials including soils, emulsion-based mixes, rollercompacted concrete, etc is desirable. The setting should enable the user to regulate compaction pressure, angle adjustment, gyrations, and adaptability for different size molds. The setting should also allow the user to switch between internal and external angle settings. • The control system should be network compatible with complete data management. • The SGC should have a capability for number and angle of gyrations, specimen height, and consolidation pressure to be sent to standalone PC, stored on a flash drive, or printed directly. • There should be an ability to set to a specified number of gyrations, specified sample height, or a locking point, at a selected internal or external angle. • Total gyrations should range from 0 to 999 at 30 ±0.5 gyrations per minute and 0° to 1.50° internal or external angle, with compaction pressure selectable from 200 to 999 kPa. • The final specimen height should be in the range of 0 to 200mm. • The SGC should have shear measurement capability to determine workability and compatibility of a mix. • Power requirements are 115V/50-60Hz.
