摘　　要：为实现新城片区绿色低碳建设,在南京南部新城城市道路建设过程中,采用了工程渣土资源化利用技术,介绍了南部新城低碳道路建设概况,提出了工程渣土资源化利用技术方案,并从道路结构耐久性提升和减排等方面论述了低碳道路技术效果。结果表明,工程渣土的固化后用以道路路基和底基层建设,可显著提升道路结构耐久性,避免了工程渣土外运和灰土外购过程中的碳排放。In order to realize the green and low-carbon construction of the new city area,the technology of engineering residue resource utilization is adopted in the urban road construction process of the southern New city of Nanjing.This paper introduces the general situation of the construction of low carbon road in southern New Town,puts forward the technical scheme of the resource utilization of engineering residue,and discusses the effect of low carbon road technology from the aspects of road structure durability improvement and emission reduction.The results show that the solidified residual soil can be used for road subgrade and subbase construction,which can significantly improve the durability of road structure.The transportation of waste soil and the purchase of grey soil are avoided,and the carbon emission in the construction process is significantly reduced.
