Vacuum Pyknometer

The Vacuum Pyknometers (Yale Pyknometer) are used for determining the theoretical maximum density of compacted or non-compacted bituminous paving mixtures (voidless mass). The Vacuum Pyknometers are used together with a Vibra-Dearator, Vacuum Pump and filter flask or air drying unit / water trap to complete the test set. Percent air voids in compacted bituminous mixtures and the amount of bitumen absorbed by the aggregates can also be calculated with the test.
