Test Importance In all bituminous works bitumen is required to be heated up to a definite temperature, so that the specific grade of bitumen may reach at its proper viscosity label, so that it can be mixed correctly with the aggregates to get a homogenous mix. Definition of Kinematic Viscosity It may be defined as …
DETERMINATION OF ABSOLUTE VISCOSITY Importance In all bituminous works bitumen is required to be heated up to a definite temperature, so that the specific grade of bitumen may reach at its proper viscosity label, so that it can be mixed correctly with the aggregates to get a homogenous mix. Definition of Absolute or Dynamic Viscosity …
