Specifications include, but are not limited to: Features•No Computer:The instrument is self-contained with push button controls and a display screen. •No Asphalt Mix Required:This minimizes the possibility that asphalt debris will affect angle measurement.•SGC Verification Performed at Room Temperature•NIST-Traceable Verification & Calibration:A RAM kit includes a calibration tube, which is used to verify the RAM.The tube is certified for one year, which provides a NIST-traceable standard.•Load Simulation: The loading method simulates the forces applied to a gyratory compactor frame from within the mold, which provides consistent frame loading with reproducible angle measurements. This approach also lets one evaluate the performance of an SGC at different tilting moments by changing the radius (eccentricity) of the contact rings on each end of the RAM. As the eccentricity increases, the applied internal moment increases. The RAM is supplied with integrated 22-mm eccentric (44-mm diameter) loading rings for typical AASHTO T 344 internal angle measurements and a pair of 32-mm eccentric (64-mm diameter) loading rings for calibrating compactors equipped with shear instrumentation.Technical Specifications•Power: 3 Volt, Lithium coin-type batteries (CR2450, 3 required)•Dimensions: Instrument: 150 mm OD X 123.5 mm H•Case: 520-mm 444-mm X 203-mm (20.5” X 17.5” X 8.0”)•Weight: Instrument: 6.4 kg (14 lbs.)
