ASTM D70 Density of Semi-Solid Bituminous Materials (Pycnometer Method)
Bituminous materials are used in road construction, roofing, water proofing and many other applications. The density of these materials is important for mass/volume conversions, estimation of binder content and prediction of the amount of material needed to obtain a desired thickness. If bitumen is to be separated by a hot water separation process, the density at the separation temperature is required. This test method determines the specific gravity (relative density) and density of semi-solid bituminous materials.
The sample is heated and poured into a pycnometer until the pycnometer is about ¾ full. It is then cooled and weighed. The remaining volume is filled with distilled water, the pycnometer is heated to the test temperature, and the final mass is recorded. The density is reported in kg/cubic meter.
