Asphalt Rice Test Equipment: Vacuum Pycnometers, Shakers & Controls
Build the Setup Around Maximum Specific Gravity
Asphalt Rice testing determines the theoretical maximum specific gravity of uncompacted asphalt mixtures. Start with the required test procedure and sample size, then select the vessel, agitation equipment, vacuum source and pressure measurement arrangement. A vacuum pycnometer alone is not a complete Rice test system.
Keep this application distinct from bulk specific gravity testing of compacted specimens. For immersion-weighing equipment and other density arrangements, review asphalt specific gravity test equipment separately.
Match the Vacuum Pycnometer and Shaker
Compare the 2000g Pycnometer with larger options such as the 6,000g Pycnometer against the specimen requirements. Check usable capacity, closure, fittings and the listed contents rather than assuming every vessel includes its supporting components.
The Rice Shaker for Specific Gravity and Asphalt Rice Test provides variable agitation and timed operation. Confirm the vessel's clamping arrangement and any adapter needed for its size and shape. A flask adapter and a large-pycnometer adapter are not automatically interchangeable.
Select Vacuum Measurement and Control
Assess the Heavy-Duty Oilless Vacuum Pump against the required performance and system connections. Check pressure-measuring equipment independently of the pump: a vacuum source does not establish that residual pressure is being measured in the required manner.
For automated pressure and timing control, compare the AutoRice Digital Manometer/Controller with PumpSaver. This configuration includes an air dryer; shaker monitoring uses a separately supplied sensor. Confirm electrical compatibility and the required connections before combining equipment.
Complete the System Before Ordering
Review tubing sizes, clamps, moisture protection, vessel adapters and calibration-document requirements against the selected components. Follow the applicable procedure and equipment instructions for sample preparation, agitation, pressure, temperature and weighing.
Record what is included with each listing and what must be ordered separately. Choose verified compatible equipment rather than treating every flask, shaker or vacuum accessory in the broader category as suitable for the same test.
