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:
- 75-D1122, heavy duty version, 10000 ml cap., specially designed for this application, made from robust transparent plastic and fit with vacuum gauge, coupling for vacuum application and vent valve. Suitable for paving mixtures samples of max. 6000 g, with maximum aggregate size of 50 mm (2”).
- 75-D1123/C, aluminium canister 4500 ml cap., with transparent lid, fit with vacuum gauge, coupling for vacuum application and vent valve. Suitable for paving mixture sample of max. 2000 g, with max. aggregate size of 19.1 mm (¾”).
- 75-D1123/D, 10000 ml cap., made from plastic with transparent cover, fit with vacuum gauge, coupling for vacuum application and vent valve. Suitable for paving mixtures sample of max. 6000 g, with max. aggregate size of 50 mm (2”).
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.
