高速公路沥青路面专项养护设计应用研究

Application Research on Special Maintenance Design of Expressway Asphalt Pavement

高速公路沥青路面养护设计是一项复杂的系统工程。采用宏观检测与细观检测相结合的方式对路面技术状况进行系统分析与评估,提出了静态设计与动态设计相结合的养护设计思路,制定了养护设计流程。通过钻芯取样分析,阐述了沥青路面典型病害发生的原因及破损层位,为制定合理的路面病害处治方案提供了设计依据,也可为高速公路沥青路面大中修养护设计与实施提供参考。

The maintenance design of expressway asphalt pavement is a kind of complex system engineering.The combination of macro inspection and micro inspection is used to systematically analyze and evaluate the technical status of pavement,the maintenance design idea of combining static design and dynamic design is put forward,and the maintenance design process is formulated.The causes of typical diseases and damaged layers of asphalt pavement are elaborated through core sampling analysis,so as to provide design basis for the formulation of the reasonable treatment scheme for pavement diseases and also provide reference for the design and implementation of large and medium-sized maintenance of expressway asphalt pavement.
