改良铁尾矿渣路基填筑施工与质量评价研究

Study on filling construction and quality evaluation of modified iron tailings slag subgrade

针对铁尾矿渣材料在路基填筑施工中的改良处理与施工质量控制问题,系统研究了铁尾矿渣的改良机理、改良铁尾矿渣施工关键控制点和施工质量评价方法,设计了水泥改良铁尾矿渣现场测试并采用现场承载板静态回弹模量测试和PFWD动态变形模量测试对施工质量进行检测。

In view of the improvement treatment and construction quality control of the iron tailed slag material in the subgrade filling construction,this paper systematically studies the improvement mechanism of iron tailings,key control points and construction quality methods of modified iron tailings slag base construction.In this paper,the field test of cement iron tailings slag base is designed,and the static modulus of resilience and dynamic modulus of resilience of PFWD are used to test the construction quality.
