EFFECT OF THE MORPHOLOGY OF SBS MODIFIED ASPHALT ON MECHANICAL PROPERTIES OF BINDER AND PERFORMANCE OF MIXTURE

SBS-modified asphalt is finding widespread application as a binder for rutting-resistant mixtures, mixtures for porous pavement, etc. The performance is greatly affected by the morphology of the SBS. In this study, we made trial SBS-modified asphalt products of varying morphologies and clarified the relation of the dispersed conditions of SBS-modified asphalt products to its performance and storage stability as the binder and various performances of paving mixtures. As a result, we could show the morphology of SBS-modified asphalt required to ensure its proper performance.
