Warm mix asphalt (WMA) additive enables the utilization of more reclaimed asphalt pavement (RAP) in road construction. However, variations in RAP properties complicate the characterization of the rheological properties of virgin binder when blended with reclaimed asphalt binder. This study presents the evaluation of rheological properties of reclaimed asphalt binder incorporating RH-WMA, a new wax based WMA additive. The reclaimed asphalt binders recovered from two road sources were blended at various percentages with 3% RH-WMA additive. The rheological evaluations were carried out from the viscosity and dynamic shear rheometer (DSR) test results. The results indicated that the incorporation of reclaimed asphalt binder into virgin binder increased the viscosity and stiffness, while addition of RH-WMA additive slightly reduced the viscosity and stiffness. A non-dimensional viscosity index indicated an …
