The Effect of Sulfur on Physical and Rheological Properties of Polymer- Modified Bitumens

Nowadays, using of SBS modified bitumens due to their favorite physical, mechanical and rheological properties increased in pavements and asphalt applications. But some defects of these binders such as high viscosity, instability in storage tank and etc. lead to several problems in use of these binders. This research investigated the interaction effects of sulfur/polymer as a function of various blending treatments in the laboratory. Physical and rheological parameters have been considered
