The results shows that storage modulus (G¡¯) is obviously less than loss modulus (G¡±), which means viscous behaviour of bitumen is dominant, and anti-rutting factor (G*£¿£¿£¿sin£¿¦Ä) is markedly enhanced by star SBS than by linear SBS. The morphology indicated that star SBS improved the softening point more obviously, tending to form a cross-linked network in bitumen. As for linear SBS, it is dispersed in bitumen in the form of globules and enhances the ductility of binder %K dynamic mechanical analysis %K anti-rutting %K microstructure %K high modulus bitumen %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=238747
