高纬度季冻地区高速公路改扩建工程路面设计方案

Design Scheme for Pavement of Reconstruction and Extension Project of Expressways in High Latitude Seasonal Frozen Area

旧路面改善设计和新旧路面拼接设计是改扩建路面设计方案的重中之重,结合高纬度季冻地区高速公路改扩建工程项目,对旧路改善设计和新旧路面拼接设计中需要注意的环节进行分析、总结,为类似工程设计提供参考。

The improvement design of old pavement and the splicing design of new and old pavement are the top priority of design scheme for the reconstruction and extension pavement.In combination with the reconstruction and extension project of expressways in high latitude seasonal frozen area,the links needing attention in the improvement design of old pavement and the splicing design of new and old pavement are analyzed and summarized,so as to provide reference for the design of similar projects.
