Abstract
Warm mix asphalt (WMA) has grown in popularity in recent times due to the energy benefits and environmental advantages. In this work, a wax-based additive called Sasobit Redux, which was induced with synthetic RAP binder and industrial waste oil, was used to lower viscosity, and hence mixing and compaction temperature during which asphalt blends are prepared in this investigation, VG30-grade bitumen binder is employed. The goal of this study is to assess the impact of a warm mix additive (Sasobit redux) incorporated with a higher percentage of rejuvenated artificial synthesis RAP binder and industrial waste oil (IWO). Four types of blends were prepared with one viscosity grade of virgin binders (VG30) induced with RAP (70%), WMA Sasobit Redux (3% and 4%), and waste oil, 41.14% dosage. It was found that adding rejuvenator to the blend has a detrimental influence on the rutting qualities, while the WMA addition improves the same, but the test results show that using 4% of WMA (Sasobit Redux) additive is far more optimal.
