Rheology of Asphalt - DSR Testing and Technology in Australia & New Zealand

Rheology of Asphalt - DSR Testing and Technology in Australia & New Zealand


For good product quality, the main focus is on the binder attributes of bitumen, which can be measured with a dynamic shear rheometer (DSR). The various processing and usage steps require different consistencies of bitumen. In road engineering, the hot asphalt-concrete mixtures are produced and homogenized at various temperatures. The asphalt plants used for continuously processing these mixtures an be stationary or mobile, so the mixture must be pumpable and pourable. During the subsequent cooling phase after application, the mixture is continuously compacted on the road.

The properties of bitumen can be optimized by testing its viscosity and other rheological parameters that describe its stiffness and compliance. Various measuring geometries and accessories, such as heating devices specialized for bitumen (or asphalt) testing ensure highly accurate results.
