SBS改性道路沥青的性能评价

对5种道路沥青改性剂进行了改性效果的对比评价实验，探讨了SBS改性沥青的改性机理，说明SBS在沥青中形成“网状结构”部分对提高改性沥青的综合性能贡献最大。然后用改性机理来研究解释改性效果。实验结果表明，添加质量分数为5％的SBS改性沥青的改性效果满足参考标准要求。另外，燕化合成橡胶厂道路沥青改性专用料SBS－1#的改性效果已达到同剂量国外SBS的质量水平，其在工程应用中也验证了这一结论。

Evaluation on the properties of SBS modifieel roadway asphalt

This paper studied and compared modifieel effect of five modifieel agents. In addition, the modifieel theory of SBS modifieel asphalt was discussed. Furthermore, the modifieel effect was explained by the modi-fieel theory. It was found that moddifieel asphalt added 5 percent SBS was enough to satisfy the standard.Moreover,special material of modifieel asphalt, SBS-1# produced by Synthetic Rubber Plant of YHPC was equivalent with foreign modifieel agent. It was proved by engineering application.
