Estimation of density and moisture content in asphalt ...

The dielectric property of materials (asphalt binder and aggregate) in asphalt mixture were directly measured by the Percometer instrument. Laboratory specimens of asphalt mixture were produced to optimize the parameters of density prediction model. Then, water was introduced into the model for the estimation of moisture content in the specimens.

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

Using a digital density meter. 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 ...
