摘　　要：本文综述了沥青路面开裂的类型,总结其形成机理;从环境因素、沥青种含量、级配类型和沥青老化等方面分析了影响沥青路面抗裂性能的因素;探讨了裂纹的防治措施,包括改善沥青混合料的配合比设计、使用改性沥青和裂缝愈合技术等方法。研究发现:目前关于沥青路面抗裂机理的研究仍有不足,后续研究应结合地域特征,完善路面开裂模型,开发更具针对性的抗裂技术,研发寿命更长的抗开裂沥青路面。This paper reviews the types of asphalt pavement cracking and summarizes its formation mechanism;analysing the factors affecting the cracking performance of asphalt pavements in terms of environmental factors,asphalt species content,grading type and asphalt aging;and exploring the crack prevention and control measures,including improving the ratio design of asphalt mixtures,the use of modified asphalt,and crack healing technology and other methods.The study concluded that the current research on the anti-cracking mechanism of asphalt pavement is still insufficient,and the subsequent research should be combined with the geographical characteristics,improve the pavement cracking model,develop more targeted anti-cracking technology,and develop longer-life anti-cracking asphalt pavement.
