چکیده مقاله
The purpose of this study is to evaluate performance of control and modified stone matrix asphalt mixtures Conventional and four modified mixtures were studied on SMA performance Ethylene vinyl acetate EVA , Elvaloy, styrene butadiene rubber SBR , and Lucobit were used as modifiers SMA mixtures containing 60/70 penetration grade unmodified bitumen and polymer modified bitumen were plant prepared with one source of aggregate For this study specimens were made and designed by Marshall method which is the most common design method in Iran Dynamic creep and indirect tensile strength tests were used for evaluation of performance of control and modified mixtures Elvaloymodified mixture has resulted to highest value of ITS and flow number It was also observed that Elvaloy modified mixture had the most resistance in view of rutting
