Evaluation of the Cohesive Properties of SBS-Modified Binders at Low Temperatures

Abstract The durability, fatigue resistance, and low-temperature behavior of asphalt layers are greatly affected by the properties bitumen. Therefore, composition bitumen is frequently modified to improve performance mixtures. Sty-rene-butadiene-styrene (SBS) has been most often used additive recently. Researchers trying cohesive adhesive binders such polymer-based additives. In this study, 160/220 penetration grade Kraton D 1101 SBS were used. present study contains a new evaluation for determining SBS-modified at -1°C, -3°C, -5°C. results compared conventional rheological test results. Penetration, softening point, viscosity, dynamic shear rheometer, bending beam rheometer tests therefore conducted. Finally, tensile found be consistent with other tests; hence, they also confirm low temperatures.
