Used for determining the theoretical maximum specific gravity of uncompacted bituminous paving mixtures. They can also be used for the calculation of the percent of air voids in compacted bituminous mixtures and the amount of bitumen absorbed by the aggregates.
We propose three models:
All the above vacuum pyknometers have to be shaked gently for the evacuation of air by the 15-D0407/B vibro-deaerator with his clamping device 15-D407/B1.
The complete set includes the vacuum pump with de-airing system. See accessories and Vacuum pumps.
