Vacuum Pyknometer (Yale Pycnometer) for Rice Test
The Vacuum Pyknometers (Yale Pyknometer) are used for determining the theoretical maximum specific gravity and density of compacted or non-compacted bituminous paving mixtures (voidless mass).Percent air voids in compacted bituminous mixtures and the amount of bitumen absorbed by the aggregates can also be calculated with the test.
UTAS-0093 consists of a 4,3 liter aluminium container, a transparent vacuum lid a aluminium volumetric lid.
UTAS-0094 consists of a 10 liter transparent plastic container, a transparent plastic vacuum lid and a transparent plastic plate.
To complete the test, vibro-deairator(UTG-0130), vacuum pump, vacuum gauge(UTGE-3552), 2 pcs. filter flask (UTGG-2016) or air drying unit / water trap (UTGE-3570) should be ordered separately, in addition to UTAS-0093 or UTAS-0094.
Vacuum Pumps are supplied with 3m plastic tube (Ø8mm OD, - UTGP-1440)) and an auto-nipple.
UTGE-3552 Vacuum gauge, analog, scale range (-100/0 kPa), accuracy (1.0 % of scale range), 1 kPa graduated, Ø63 mm. Supplied with a valve, 4-way dispenser muffler and. its hanger.
