WebAR2000 Rheometer. System: Made by TA Instruments, the AR2000 can subject a fluid to the full range of shearing motions: steady, oscillatory, startup and cessation. Hence the instrument can measure: Viscosity, as a function of shear rate (the flow curve) Dynamic properties, the shear modulus G’ and the storage modulus G”. A dynamic shear rheometer, commonly known as DSR, is used for research and development as well as for quality control in the manufacture of a wide range of materials. Dynamic shear rheometers have been used since 1993 when Superpave was used for characterising and understanding high temperature rheological properties of asphalt binders in both the molten and solid state and is fundamental in order formulate the chemistry and predict the end-use perform…
