  • Effect of Encapsulation Combined with Microwave Heating on Self-Healing Performance of Asphalt Mixture
  • Abstract As an innovative maintenance technology of asphalt pavement, encapsulated rejuvenator used to improve its self-healing performance has been widely investigated by researchers in recent years. In this work, the selfhealing properties of asphalt mixture with and without encapsulations were comparatively studied considering these parameters: Healing time, healing cycles and microwave heating. Three-point bending strength recovery test and fatigue loading cycles recovery test were conducted for two kinds of encapsulations containing the healing agents present inside the asphalt mixture, namely compartmented Ca-alginate/SiO2 fiber and compartmented Ca-alginate/graphene oxide fiber. The results showed that the optimum healing time was three days. After the…
