The investigation and comparison effects of SBS and SBS with new reactive terpolymer on the rheological properties of bitumen

► The effect of styrene-butadiene-styrene (SBS) and SBS + Entira®Bond 8 additives on characteristics of bitumen was investigated. ► The results showed that both polymers groups reduce temperature susceptibility of bitumen. ► SBS + Entira®Bond 8 modifications improved the properties of bitumen better than just SBS modifications.
