Heavy traffic roads combined with large ranges of temperature lead an extensive attention to improve asphalt’ s performance and durability. This modification intend to offer enhanced strength and stability at both temperature extremes. Nowadays, the addition of polymers and commercial carbon blacks (CBc) are the most frequent. The scrap tyre-derived carbon black (CBp) investigated in this work, has some similar physico-chemical properties comparing to CBc. On the other hand, environmental and bitumen producers are relying on the road construction industry to develop markets for some waste materials which can be cheaply used as reinforcing agents. These aspects together motivate our interest in studying CBp modified asphalt binders. In this perspective, commercial carbon black (CBc) designated ASTM N 5 5 0 and pyrolytic carbon black (CBp), a by-product of scrap tyre pyrolysis, were compared as modifiers in twodifferent bitumen grades. Standard tests suchaspenetrability, softening and Fraass breaking points, were performed on straight and modified binders at different CBp and CBc concentrations. Linear viscoelastic properties were also studied at temperatures ranging from 0°C to 60°C. Comparing to the used commercial carbon black, the CBp revealed a good potential as a reinforcing agent. The study suggested that for warm climates, the addition ofpyrolytic carbon black may be useful in increasing the rigidity and the elasticity ofbinders. It also reduces the rutting potential for heavy road traffic pavement sections. The lower susceptibility to crack propagation is exhibited with 5 to 15% CBp blends
