新铁高速公路预防性养护维修设计方案研究

Research on the Design Scheme for Preventive Maintenance and Repair of Xintie Expressway

通过收集新铁高速公路原设计资料,确定了维修设计范围。整理交通量数据,掌握了道路运营各车型的占比及主要营运车型。在实际调查的基础上,分析各检测指标,明确了影响路面技术状况指数的主要因素。综合以上因素,确定了预防性养护的罩面材料和总体方案。

By collecting the original design data of Xintie expressway,the maintenance design scope is determined.The proportion of each vehicle type in road operation and the main vehicle types in operation are mastered by collating the traffic volume data.On the basis of the actual investigation,the detection indicators are analyzed,and the main factors affecting the pavement technical condition index are clarified.Based on the above factors,the overlaying materials and the overall scheme for preventive maintenance are determined.
