| Abstract: | A system whose partial information is known and partial information is unknown is called gray system. In this paper, the compatibility relationship between Styrene-Butadiene-Styrene (SBS) modifier and base asphalt composition was studied by correlation analysis method. The analysis results of correlation level show that aromatics and asphaltene of base asphalt affect SBS modified effect mainly as the content of SBS is lower, while the content of aromatics and resin become the main effect factors as SBS content is increased. |
