摘　　要：层间接触条件影响界面强度,改变了路面结构应力、应变,影响路面标明弯沉.总结了层间界面力学特性的影响因素和试验方法,并评述各因素和试验方法的优缺点.同时,归纳了表征层间界面力学特性的技术指标和模型,这些为进一步研究层间界面力学与路用性能的关系、研究表征层间界面动态技术指标及其与路面结构设计提供了文献基础.Highway performance of asphalt concrete pavement was partly influenced by the interface mechanical strengths of pavement structural layers.A lesser interface strength results in all kinds of destroying on the pavement.Hence,it is very important to study the interface mechanical properties.Interlayer contact condition has an important effect on the interface strength,changes stress and strain of pavement structure,and influences deflection on the pavement surface.A few influencing factors and some testing methods are reviewed by thoroughly analyzing their merits and demerits,some technical indexes and models which interpreted interface properties are summarized,and the relationship between interface mechanical properties and highway performance with interface mechanical indexes and pavement design are investigated.
