摘要
沥青混合料在承受外界载荷和环境的破坏时,物质的传输和应力的传递都是通过沥青—集料界面,所以其在沥青混合料中起到了一个至关重要的作用。目前研究人员采用多采用表面能理论对其界面的粘附性进行定量的表征,用来衡量界面性能的优劣。通过表面能理论分析了影响界面性能的因素,并通过相应的处理方法对界面的结构和组成进行优化。
When the asphalt mixture is subjected to external load and environmental damage, the material transmission and stress transmission are through the asphalt-aggregate interface, so it plays a vital role in the asphalt mixture. At present, researchers use the surface energy theory to quantitatively characterize the adhesion of the interface to measure the performance of the interface. The factors affecting the interface performance were analyzed by the surface energy theory, and the structure and composition of the interface were optimized by the corresponding processing methods.
