خلاصه مقاله:
In recent decades, using polymers to improve bitumen properties is increasing. In 1960`s the copolymerization techniques developed and Styrene - Butadiene - Styrene (SBS), one of themost effective additives which has plastic and thermoplastic properties at the same time, has been offered in bitumen market. This polymer will improve the properties of bitumen both in high (FBP= 130c) and low (FBP=-38 c) temperatures, then it is practicable for all weather conditions and itsperformance will be satisfying in both conditions. In this research the effects of SBS polymer on bitumen and asphalt was studied. Pastexaminations shows that SBS polymer will decrease the Frass breaking point and lose weight of bitumen and also increase the softening point and penetration grade of it. SBS polymer also improves the properties of asphalt, including the increase of MarshallResistance and flow of asphalt mixtures; but it has no considerable effect on specific gravity of asphalt; and at the same time decreases the optimal bitumen percentage of asphalt.
