Measuring the density of bitumen/asphalt :: Anton Paar Wiki

The standard test method (ASTM D8188) requires a digital density meter to measure the asphalt/bitumen samples. A density meter requires less sample volume (around 3 mL to 4 mL, which is about half the amount needed by pycnometers). The density meter used ideally must have a way to keep the syringe at a temperature of around 130 °C to 140 °C ...
