Pine Test Equipment’s G2 Superpave Gyratory Compactor makes asphalt and soil specimens.
The System
An electromechanical system with integrated controls and angle of gyration measurement drives the G2. Users define compaction mode, specimen size, number of gyrations, target height, pressure, and angle of gyrations using the control panel. The G2 compacts material at a constant pressure and angle of gyration. It gyrates at a fixed speed. An integrated extruder conveniently expels specimens from molds. The enclosed compaction chamber keeps the user safe. And, two USB ports and an Ethernet jack make exporting and printing compaction data easy.
Different Specimen Sizes
The G2 accommodates 150- and 100-mm specimens. Pine manufactures the standard machine to make 150-mm specimens. However, the 100-mm Conversion Kit along with a 100-mm Mold Assembly allow for the compaction of 100-mm specimens.
Cooling Specimens in Place
Some asphalt mixes containing rubber expand while cooling if the specimen is not constrained. Holding the specimen in the machine until it cools addresses this problem. Pine provides an optional Cooling Door Kit for the G2. A fan in the door accelerates specimen cooling. And, a shorter cooling time increases potential machine throughput.
Compaction Modes
Pine’s G2 Superpave Gyratory Compactor runs three compaction modes. Number of Gyrations applies a user-defined number of gyrations to the specimen. Compact to Height concludes compaction when a user-defined height is reached. Locking Points stops compaction when the height change between subsequent gyrations is equal to or less than a user-specified height change.
A User Favorite
Customers love the G2 because it is simple to operate, the machine functions consistently, G2’s experience few problems, and Pine supports it well.
Optional Gyratory Shear
Outfit your Pine G2 Superpave Gyratory compactor to measure and record gyratory shear as an optional feature.

What should be considered in identifying a location for a machine?
- A sturdy, approximately level floor is important. The machine weighs about 880 lb. (400 kg) and is top heavy.
- The machine can be installed in a mobile lab. Holes are provided in the lower frame bracket to secure the machine to the floor.
- The minimum floor space requirement is 34.5 inches wide by 35.5 inches deep. Be sure to allow additional space on the right side of the machine for access to the USB data port.
- Allow space on either side of the machine for access to service it when necessary if there is insufficient room to move the machine around for servicing.
- The minimum vertical space necessary is about 54 inches.
- Provide access to an appropriate power supply for the machine purchased.
How movable is the machine?
- The machine comes with a set of wheels and handles installed. Once the machine is off the skid, it can be moved a short distance by a single person. Care must be taken, however, because of the machine’s high center of gravity.
- Three (3) lifting eyes are located on the top of the machine to provide a proper location to connect lifting apparatus.
- The lower frame of the machine is configured to receive fork truck forks.
How often does a machine need calibrated?
- AASHTO R 18 specifies that a gyratory compactor should be verified every 12 months.
- ASTM D6925-15 Section 6.2 specifies that a gyratory compactor should be calibrated annually or whenever there is reason to doubt the stability of the machine’s operation.
- AASHTO R 18 Section 6.2.1.3. specifies that equipment that may be affected by moving it to a new location or environment should be calibrated, standardized, or checked before being placed into service.
- ASTM D6925-15 Section 6.3 specifies that calibration should be verified after it is moved to a new location.
