## 4 Conclusions  
This research investigated the effects of three warm mix additives on the physical properties of rubberized asphalt binder by performing physical tests, namely the penetration, softening point, penetration index, penetration viscosity number, storage stability, ductility, viscosity test, and stiffness modulus. Based on the research results, the researchers draw the following conclusions. \begin{table}

Notably, the binder that underwent modification through the introduction of crumb rubber and Sasobit showcases the most pronounced hardness. * All rubberized asphalt binders modified with warm mix asphalt (WMA) techniques manifest elevated values of softening points in comparison to the original asphalt binder. Among these alternatives, the rubberized asphalt binder that incorporates Sasobit stands out with the highest softening point. * The penetration index, penetration viscosity number, and loss on heating of crumb rubber with WMA additives closely resemble those of the virgin asphalt binder. * The modified asphalt binders exhibit commendable stability over the course of storage. * With the exception of the rubberized asphalt binder adjusted with Rediset, all other modified asphalt binders adhere to the criteria set by the ductility test. * All pairings of rubberized asphalt binder and WMA additives contribute to the reduction of viscosity values. Notably, the rubberized asphalt binder with Sasobit showcases superior workability compared to its counterparts employing alternative WMA additives. * Among the assortment of asphalt binders, the combination that involves crumb rubber and Sasobit-modified binder presents the highest stiffness modulus values under conditions of intermediate and high temperatures. * When subjected to lower temperatures and briefer loading periods, the blend of Rediset and crumb rubber produces the most significant stiffness modulus values.
