Viscosity Grading - Pavement Interactive
Kinematic Viscosity. The kinematic viscosity of a liquid is the absolute (or dynamic) viscosity divided by the density of the liquid at the temperature of measurement. The 135 ° C (275 ° F) measurement temperature was chosen to simulate the mixing and laydown temperatures typically encountered in HMA pavement construction.
