The neat bitumen, an oil refining by-product, has its own inherent weakness under long-time loading at low and high temperatures. These performance limitations of neat bitumen have led researchers to modify its physical andmechanical properties. According to several studies, polymers can be used to modify the properties of bitumen. Due to much lower production costs and aiming to reduce environmental impacts, recycled waste polymers are preferred as compared with virgin polymers. In this study, the effect of recycled waste polymers including crumb rubber modifier (CRM), polyethylene and latex and non-polymeric materials such as natural bitumen (NB) and heavy vacuum slops (HVS) cut on physical and mechanical properties of vacuum bottom residue (VB) of crude oil distillation was investigat-ed. Based on the results, recycled waste polyethylene and NB can improve the performance grade of VB at high temperatures and CRM, latex and HVS can improve the performance grade of VB at low temperatures. Thus, by designing various blends of these additives with VB, different modified bitumens can be directly obtained from VB without any need to air-blowing process
