The Rotational Viscometer (RV) is used to measure the dynamic viscosity of asphalt binders at different temperatures. The RV data are used to determine the appropriate temperatures for mixing and production of asphalt mixes. Since production compaction temperatures of asphalt mixes are quite high, the test is usually conducted at elevated temperatures such as 135°C.

Therefore, a viscosity of 3000 cP is not exceeded at 135 °C, and the asphalt binders can therefore be pumped and handled at the hot-mixing facility [ 5 ].
