Abstract

      These days, there are many new materials used in asphalt concrete pavement, especially polymer modifiers, but their effects are not enough good. As a result, a well-known polymer modifier in asphalt in the world which is Styrene-Butadiene-Styrene (SBS) is used with asphalt binder 60/70 in this study. Some main properties of polymer modifier asphalt such as penetration, softening point, elastic recovery, kinematic viscosity, storage stability, and adhesion are tested with four percent of SBS such as 2, 4, 6, and 8% in order to analyse the effect of SBS percent to asphalt properties. This paper also shows the mixing procedure of SBS and asphalt binder with penetration grade of 60/70 by using high speed rotating mixer.
