The DSR is a dynamic shear Rheometer apparatus used to characterize the viscous and elastic behavior of bituminous binders. The DSR system enables measurement of flow properties (such as shear viscosity from flow tests) and dynamic material properties (such as viscoelastic modulus and phase angle from oscillation tests) and dynamic material properties (such as viscoelastic modulus and phase angle from oscillation tests) according to Asphalt industry standards.
DSR robust construction makes it durable even under tough working conditions.
Determination of complex shear modulus G and phase angle.
