Evaluation of Rutting Parameters of Asphalt Binder Based on Rheological Test

Chao Wang and Jinxi Zhang
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.

Index Terms—Asphalt binder, rheological test, rutting parameters, correlation analysis.
