摘要
纳米材料作为一种超微粒材料,因其优异的性能在沥青改性方面备受欢迎,且改性效果显著。在此基础上,研究者进行了更深层次的探索,对纳米材料复合聚合物改性沥青进行了更广泛的研究。主要介绍了3种改性效果优异的纳米材料/SBS复合改性沥青及其制备方法和性能评价;然后介绍了复合改性的改性机理;最后提出了纳米材料/聚合物改性沥青今后可能的几个发展方向。
As a kind of ultrafine granular material, nanomaterial is popular in asphalt modification because of its excellent performance, and the modification effect is remarkable. On this basis, researchers have made further exploration, and conducted a more extensive study on nanomaterial composite modified asphalt. In this paper, several kinds of nanomaterials/SBS composite modified asphalt with excellent modification effect were mainly introduced,as well as their preparation methods and performance evaluation. Then, the modification mechanism of compound modification was introduced. Finally, several possible development directions of nanomaterial/polymer modified asphalt in the future were put forward.
