摘　　要：刚柔复合式路面作为一种耐久性路面结构,广泛应用于重载交通、特殊地质条件、桥隧铺装等工程。为进一步推动耐久性刚柔复合式路面的应用,明确研究中的关键问题及发展方向,该文综述了国内外刚柔复合式路面的相关研究进展。在梳理刚柔复合式路面结构设计理论及施工技术的基础上,首先阐述了刚柔复合式路面的结构力学行为特征,分析了沥青面层和刚性基层的荷载应力、温度应力及其交互影响,刚性基层上的沥青面层一方面直接承受荷载和环境作用,另一方面可以改善下卧结构层的应力场和温度场,是影响刚柔复合式路面服役性能及使用寿命的关键;明确了刚柔复合式路面的病害主要出现在沥青面层,由于沥青面层与刚性基层之间的模量差异巨大,刚性基层上的沥青面层更倾向于产生压剪破坏,刚性基层的开裂以及刚‒柔层间的结合状态对沥青路面的性能也有着显著影响;最后,分别从沥青面层抗剪、基层板整体性、刚‒柔层间结合3个方面归纳了刚柔复合式路面性能的提升技术。基于刚柔复合式路面的结构力学特性,开展结构‒高性能材料一体化设计是提升刚柔复合式路面使用性能和耐久性的有效途径。The rigid-flexible composite pavement,as a kind of durable pavement structure,has been widely used for heavy-duty traffic,special geological conditions,bridge tunnel paving,etc.In order to promote the application of durable rigid-flexible composite pavements and clarify the key research issues and development directions,relevant research progress of rigid-flexible composite pavements in China and abroad was reviewed.Based on the structure design theory and construction technology of rigid-flexible composite pavements,the structural mechanical behavior characteristics of rigid-flexible composite pavements were described,and the stress induced by load and temperature of asphalt surface layer and rigid base layer,as well as their interactions were analyzed.The asphalt surface layer on the rigid base layer was directly subjected to the load and environmental effects and improved the stress and temperature fields of the underlying structural layer.It was the key factor influencing the performance and service life of rigid-flexible composite pavements.It was identified that diseases of rigid-flexible composite pavements mainly appeared in the asphalt surface layer.Due to the huge modulus difference between the asphalt surface layer and the rigid base layer,the asphalt surface layer on the rigid base layer was more prone to produce compression-shear failure.The cracking of the rigid base layer and the bonding state between rigid and flexible layers also played an important role in the performance of asphalt pavements.Finally,the technology of improving the performance of rigid-flexible composite pavements was summarized from three aspects:shear resistance of asphalt surface layer,integrity of base panel,and bonding between the flexible and rigid layers.It was an effective way to improve the performance and durability of rigid-flexible composite pavements by conducting integrated structure-highperformance material design based on the structural mechanical characteristics of rigid-flexible composite pavements.
