The DSR  measures the viscous and elastic properties of a thin asphalt binder sample sandwiched between an oscillating and a fixed plate. As the force (shear stress) is applied to the asphalt by the spindle, the DSR measures the response (shear strain) of the asphalt to the force. The relationship between the applied stress and the resulting strain in the DSR quantifies both types of behavior, and provides information necessary to calculate two important asphalt binder properties: the complex shear modulus (G* -"G star") and phase angle ("delta").  G* is the ratio of maximum shear stress to maximum shear strain. The time lag between the applied stress and the resulting strain is the phase angle. Software will be included: The origional software is on 3.5 Floppy disks which I have converted to CD.
