【摘要】 通过拉拔试验研究两种体系的界面改性剂(油溶性、水溶性)及配套改性工艺对酸性集料与沥青粘附性能的影响,使用扫描电子显微镜与DSR流变分析等技术手段研究改性机理.结果表明,界面改性剂通过薄膜改性工艺均匀的覆盖于石料表面,改变了集料的表面性质,可提高集料与沥青粘附性能,进而提高沥青路面的路用性能.

【Abstract】 The influence of two types of interface modifier(oil-soluble and water-soluble)and the corresponding modification process on the adhesion performance of acidic aggregate and asphalt was studied by puff-out test.And the modification mechanism was analyzed by the scanning electron microscopy and DSR rheological analysis technology.The results show that,due to the interface modifier covered evenly on the surface of stone through the membrane modification process,the surface properties of aggregate is changed and the adhesion performance of aggregate and asphalt is improved,and then the pavement performance is also improved.
