H1820/H1850
The Vacuum pycnometer is suitable for determining the theoretical maximum specific gravity and density of compacted or noncompacted bituminous paving mixtures, and percent air voids in compacted bituminous mixtures can also be calculated with the test.
This method is not suitable for asphalt mixtures with porous aggregates with water absorption greater than 3%.
