Abstract: The discarding of scrap tires is a serious environmental hazard worldwide. Simultaneously, the asphalt mixture containing neat binders do not always perform as required. Therefore, various efforts have been taken in the past to enhance the performance properties of the neat asphalt cements by modifying them with crumb rubber powder. Consequently, this will decrease the environmental hazards of waste tires. According to prior and ongoing research, the modification of asphalt mixtures using crumb rubber have enhanced the asphalt mixtures properties such as low and high temperature performance as well as rutting deformation resistance, fatigue cracking resistance. This paper affords via an overview of the physical and rheological properties of the rubberized asphalt binders under different conditions. This review transacts through the impact of crumb rubber particles on the asphalt binder’s workability, rotational viscosity, the needle penetration, softening point, low- temperature and high-temperature performance. Furthermore, fatigue cracking resistance, rutting behavior and storage stability are in the focus.
