| 摘 要： | 阿拉尔市道路受盐胀-冻胀变形较严重,通过对市内10条沥青混凝土道路路面破损情况进行调查和评估,结合市区土质、水文、气候及路面结构条件,分析道路结构盐胀-冻胀变形原因,针对盐分、水分影响,提出路基填料去盐处理和道路结构排水、防水措施.结果表明：改建道路中采用级配碎石基层、设置高挡水墙和基底隔断层等措施取得了较好的排水、防水效果,可为后期市区道路改建提供参考.

| Abstract: | The deformation of salt-frost in urban road is very serious in Alar. This paper assessed the condition of damaged pavement and analyzed the causes of damage after the investigation into 10 urban roads with asphalt pavement in the city. Combining with the urban soil, hydrology, climate and pave- ment of road, it also analyzed the causes for deformation of salt-frost in urban road. Then, it put for- ward some measures for removing salt which in subgrade fillings and drainage and waterproofing of road structure aiming at effects of salinity and water. The measures that apply graded aggregate base and set high water retaining wall and isolation layer under base in road rebuilding achieve good perfor- mance on drainage and waterproofing. It will provide some suggestions for the later urban road recon- struction project. |
