Evaluation
of Pine AFG2 Superpave Gyratory Compactor
• Looks like an AFG1
The AFG2 is our next generation gyratory compactor.
In this update of the dependable AFG1 compactor, we have incorporated features
that today’s mix design laboratories need in a gyratory compactor while
retaining the reliable performance of the AFG1. Operation is much like
the AFG1 and the AFG2 uses the same molds.
• Programmable Angle of Gyration
The AFG2 can operate using either an internal or
external angle of gyration over a range of 0.0° to 1.50° by simply entering
the desired angle. This permits the use of the compactor over various angle
specifications without recalibration and ensures the compactor will be
fully capable of meeting future requirements.
• Shear Instrumentation (optional)
The AFG2 can be equipped with load-cells to measure
the force required to gyrate the specimen. This is typically referred to
as gyratory shear. PinePave Excel templates are provided to graph the data
as tilting moment (N-m) or gyratory shear (kPa) vs. gyration and shear
(kPa) vs. % air-voids. The shear measurement instrumentation and internal
angle of gyration are standardized using Pine’s AFLS1 internal angle measurement
kit.
• Designed for various tasks
The AFG2 is compatible with the compaction of soils
and emulsion based mixes with protective covers over sensitive components.
The AFG2 can be programmed to compact to number of gyrations, specified
height, or to a specified change in height per gyration, sometimes referred
to as locking point.
• Performance Test Specimens
The AFG2 has been designed to compact the
tall specimens needed for performance testing. AFG2 users have reported
compacting 150mm diameter X 200 mm tall specimens.
• Complete Data Management
The AFG2 is network compatible. The gyration number,
specimen height, angle, pressure, and shear moment (optional) are all measured
and stored during the compaction process. Test data can be saved to a USB
memory stick, printed directly with the optional printer kit, or accessed
and printed through an Ethernet connection to a computer network or stand
alone computer. For convenience, data for 20 tests are also stored on the
AFG2.
