The kinematic viscosity of a fluid is the ratio of the absolute viscosity to density. It is obtained by dividing the absolute viscosity by the density. The basic test for kinematic viscosity measures the time it takes for a fixed volume of the bitumen to be drawn up through a capillary tube (viscometer) under an accurately reproducible head at a controlled temperature. It is typically measured at 60°C (140°F) and 135°C (275°F).

 

The data entry and calculations for this test are performed on the Asphalt Viscosity form described in the next section. After the data and calculations have been performed the results are displayed in a test report as described in the  reporting section below. The format of this report is controlled by the geotechnical template used for the test.

 

The methodology and calculations for this test adhere to "ASTM D 2170-01a Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)". For more detailed information on the methodology and calculations please review this standard.
