沥青路面初期损坏特点及机制分析

Analysis on the Initial Damage Characteristic and Mechanism of Asphalt Pavement

受各种内在因素和外在因素的影响,沥青混凝土路面易出现不同程度的损坏。鉴于此,文章以某二级公路为研究对象,对其初期损坏类型进行调查。针对裂缝、车辙、泛油、内部松散等初期损坏的特点开展分析,并从定性和定量两方面阐述沥青路面初期损坏机制,研究成果可为沥青路面建设和管养提供理论依据。

Affected by various internal and external factors,asphalt concrete pavement is prone to different degrees of damage.In view of this,this paper takes a secondary highway as the research object to investigate its initial damage types.Subsequently,the characteristics of initial damage such as cracks,ruts,oil spill,and internal looseness are analyzed,and the initial damage mechanism of asphalt pavement is elaborated from both qualitative and quantitative aspects.The research results can provide a theoretical basis for the construction and maintenance of asphalt pavement.
