| 摘 要： | 从基础沥青、苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）加入量、SBS化学结构、相对分子质量、嵌段比、凝胶含量、膨化度等方面分析了原料对改性沥青性能的影响。并指出提高SBS改性沥青性能的主要措施为SBS的加入量控制在4％～6％；并根据基础沥青的芳香分含量调整SBS的嵌段比等。

| Abstract: | The influence of raw materials on modified asphalt properties was analyzed from basis asphalt, the SBS content in modified asphalt, chemical structure of SBS, relative molecular weight of SBS, rate of styrene to butadiene in SBS, the SBS content in gel and swelling degree of SBS. The important measure of SBS modified asphalt properties improved was 4%-6% of SBS additive volume. In order to improve modified asphalt properties with SBS, the rate of Styrene to butadiene of SBS was controlled in accordance with the aromatic content of basis asphalt in use, and relatively large molecular weight appropriate to raise some modified asphalt performance. |
