Abstract:　Similar to engineering materials used in civil engineering, aerospace engineering and other applications, an asphalt concrete also suffers from fatigue cracking due to a cyclic loading conditions on the road, which results in a decrease of the stiffness and the strength. The self healing capability has been investigated widely due to its unique contribution to the recovery of the stiffness and the strength from cracking and then to extend the service life of asphalt pavements. In this paper, general concepts of self healing and self healing asphalt concrete were introduced. Then, the parameters that influence the self healing capability of the asphalt binder and asphalt concrete were discussed.Inspired from other self healing materials, the possibilities of applying microcapsule self healing system in asphalt concrete were investigated in detail.

摘 要：類似于工程材料用于土木工程、航空航天工程和其他應用，瀝青混凝土同樣也運用遭受疲勞開裂由于循環(huán)加載條件下的公路，這導致了剛度和強度的降低。由于其獨特的修復剛度和增加抗擊強度的能力，然后延長瀝青路面的壽命，自我修復能力已被廣泛研究。這篇文章主要介紹了自我修復的總體概念以及瀝青混凝土的自我修復的工藝。同時也對影響自我修復能力的粘合劑和瀝青混凝土的參數(shù)進行了討論。設計靈感來自其他自我修復的材料，應用微膠囊自我療愈系統(tǒng)的可能性在瀝青混凝土進行細節(jié)。
