Abstract—This study evaluated the rutting potential of two types of asphalt binders namely the neat binder and SBS modified binder by respectively using the oscillation-based parameter G﹡/sin δ and the oscillation-based nonrecoverable stiffness parameter G*/(1–(1/tanδsinδ)) as well as the MSCR-based nonrecoverable compliance Jnr. Both original and short-term aged asphalt binders were tested in this evaluation. Test results indicates that the parameter G*/(1–(1/tanδsinδ)) exhibits a stronger correlation with the parameter Nonrecoverable Compliance Jnr than that of parameter G﹡/sin δ which means the parameter G*/(1–(1/tanδsinδ)) can capture well the nonrecoverable response and should be a better choice than G﹡/sin δ when using the oscillation test to evaluate the rutting potential of asphalt binder.
