Vacuum Pyknometers

Bitumen Mixture Theoretical Maximum Specific Gravity and Density Tester Machine

1. It used to determine the theoretical maximum specific gravity of non compacted bituminous paving mixtures
2. Standard : EN 12697-5, ASTM D2041

The Vacuum Pyknometers are used for determining the theoretical maximum specific gravity and density of non-compacted bituminous paving mixtures. 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.
