| 中文摘要: |
| 基于海绵城市理念的高速公路排水系统，利用排水设施和排水结构，与自然水系和人工沟渠相连，实现路域水回收利用。通过出水口、流水槽、边沟等排水设施，将路域水汇集排出；在道路结构层内部，上面层采用大空隙排水路面，基层选用大粒径沥青稳定碎石配以横向排水管，路基内部设计纵横向排水通道，多方位、分层次的将整个道路结构层的水排出。高速公路排水系统设计引入海绵城市理念，减少道路水损坏和养护成本，实现路域水的资源化利用，经济社会效益显著。 |
| 英文摘要: |
| Based on the sponge concept of highway drainage system，the drainage facilities and drainage structures are connected with natural water system and artificial ditch to realize water recycling in the road area. Through the drainage facilities such as water outlet，water trough，edge ditch as well as other drainage facilities，the road area water is collected and discharged. In the road structure layer，the upper layer adopts the large gap drainage pavement，and the base selection is selected with large particle asphalt stabilized macadam to match the horizontal drainage pipe. Based on this， the water is discharged in a multidimensional and hierarchical manner. By introducing the idea of the sponge city，the highway drainage system reduces the damage and maintenance cost of the road water and realizes the utilization of the resource of the road area water. The economic and social benefit is remarkable. |
