New Test Method for Determining Intermediate- and Low-Temperature Rheological Properties of Asphalt Binders Using a Dynamic Shear Rheometer (DSR)
1. Scope
1.1. This test method covers the determination of parameters calculated from the measurement of modulus (G*) and phase angle (d) of asphalt binders when tested in dynamic (oscillatory) shear using parallel plate geometry in accordance with ASTM D7175. These parameters are considered important to the design of roofing binders, but will also be applicable to other paving and industrial applications that require a greater knowledge of rheological parameters relating to performance.
This test method provides a means of using rheological measurements for characterizing the hardness and relaxation properties of an asphalt binder in the high-stiffness region. Target users are those who design asphalt binders for roofing applications
