摘要
界面改性剂通过改善沥青混合料中最薄弱的环节——沥青与集料之间的界面,改善沥青混合料路用性能。研究表明,界面改性剂可以多方面提高沥青混合料的路用性能,尤其对沥青混合料的高温性能影响显著,对水稳定性、疲劳性能、低温性能也具有积极的影响。文中采用电镜扫描以及流变学的试验方法分析了界面改性剂改善路用性能的机理。
The asphalt mixture performance can be improved obviously by interfacial modified additives.The interfacial performance of asphalt and aggregate can be enhanced by interfacial modified additives.It was indicated that the interfacial modified additive improved the performance of asphalt mixture,especially high temperature performance.It contributes to water stability,fatigue performance and low temperature performance.The mechanism has been analyzed by SEM and rheology methodology.
