Density of Semi-Solid Bitumous Materials (Pycnometer Method)
ASTM D70, NFT 66007
This test method covers determination of specific gravity and density of semi - solid bituminous materials, asphalt cements and soft tar pitches. This test is carried out a temperature of 25�C � 0,2�C using a pycnometer.
Pycnometer 24 to 30ml, maximum weight 40g, and T 100 thermostatic bath with temperature range from 5�C above surrounding to +250 �C. This model is equipped with a cooling coil allowing connection to a cooling source for a regulation down to 5�C above the cooling source.
