Abstract

Because of important role of pavement quality on the safety and comfort of road users and reducing the operation period costs, the researchers have paved the way for asphalt pavement to produce improved asphalt, to increase its strength and durability against traffic load and conditions Weather. Today polymers are also bituminous modifying additives that are widely used in asphalt. In this study, three polymer with names Styrenine-Butadiene-Styrene, Styrene-Butadiene-Rubber and PolyStyrene were used to improve moisture and rutting asphalt resistance. Styrene-butadiene-styrene has a favorable experience in repair of pavement damage, but imported and due to its price dependence on political occasions, the researchers sought to combine the production of internal polymers efficiently and at reasonable prices Replace it. In this regard, two polymers of styrene-butadiene-styrene and polystyrene were mixed in 25/75, 50/50 and 75/25 combination ratios and 3 and 5% by weight of bitumen in asphalt mixtures. Marshall Stability, Indirect Tensile Strength, Resilient Modulus and Rutting tests were performed on modified specimens. The results showed that the use of polymer blends is much more efficient than the use of polymers individually, and a polymer blend containing 75% styrene butadiene, along with 25% polystyrene, can produce moisture and rutting resistance equal to styrene butadiene styrene.
