Experimental Determination of Poisson’s Ratio for Asphalt Binders at Low Temperature

A key material parameter is the Poisson’s ratio. Poisson's ratio is related to the bulk modulus, shear modulus, and Young's modulus, and it is used to determine how the material behaves under various mechanical loading configurations. The current Performance Grade (PG) specification for asphalt binders is based on tests performed in shear using Dynamic Shear Rheometer (DSR) and in bending using the Bending Beam Rheometer (BBR).
