Abstract
Pure bitumen which is used as a binder for asphalt has some functional limitations. Many works have been done to resolve these problems to develop better bitumen. The polymer modifiers are the most popular substances for these kinds of transformations. Many research approaches have been pursued to improve the bitumen quality as well as production cost reduction. Polysulfide polymer (PSP) which also can be gotten by synthesizing of Petrochemical Wastes (wPSP), is used as a modifier for bitumen in this research. Different weight percentages (1, 3 and 5) of PSP were mixed with Bitumen 60/70 from Tehran Refinery and then physical and mechanical properties of the results were experimented and compared. The results were shown that PSP was dispersed homogenized and increased the penetration, the softening point and also the penetration index. It also decreased the flashing point while the ductility and weight loss percentage stayed the same. The blend viscosity increase was the other result of this research. Using wPSP as oppose to PSP not only was more efficient but also could help to save the environment better.
