Device for measuring the deformation response of the material to an applied shear stress. Measurement is possible in both the controlled shear stress (CSS) and under controlled shear rate (CSR). The measuring cell is equipped with a Peltier element, which enables fast and accurate temperature control of the selected temperature. The device is used to characterize asphalt binders according to the American SUPERPAVE system and non-standard rheological tests with a wide range of adjustable parameters.
