The DSR measures the viscoelastic properties of bitumen, specifically the complex shear modulus (G*), which indicates stiffness, and the phase angle (δ), representing the balance between elastic and viscous behavior. These parameters help predict how the binder will perform under various temperatures and loading frequencies, crucial for pavement design.
