| 摘 要： | 良好的沥青质量是保证沥青混合料质量的前提和基础,为改善普通沥青的高温性能,借以提高沥青混合料的质量,本文通过在伦特70#和盘锦90#两种普通沥青中分别掺入不同剂量的纳米膨润土,系统研究纳米掺量对改性沥青针入度、软化点、延度等性能指标的影响规律,进而确定了改性沥青中的最佳纳米膨润土掺入量,有利于提高改性沥青及沥青混合料的耐高温性能。

| Abstract: | Good asphalt quality is the premise and foundation for ensuring the quality of asphalt mixture. In order to improve the performance of ordinary asphalt under the high temperature and the quality of asphalt mixture, the effects of nano-bentonite on the properties of modified asphalt injection, softening point and elongation were systematically studied by adding different content of nano-bentonite into the two common bitumen of Lent 70^# and Panjin 90^# respectively in this paper. The optimum amount of nano-bentonite admixed in modified asphalt is determined, which is beneficial to improving the high temperature resistance of modified asphalt and asphalt mixture. |
