Torque required to rotate a spindle immersed in the specimen is measured and yields a proportional dynamic viscosity value.
Asphalt binder products are tested for pumping characteristics and temperature/viscosity charts can be developed to estimate mixing and compaction temperatures in hot-mix design.
