Improved collapsible loess roadbed, filler, filler preparation method and roadbed construction method
The invention discloses an improved collapsible loess roadbed, a filler, a filler preparation method and a roadbed construction method, and belongs to the technical field of roadbeds. The improved collapsible loess roadbed filler comprises lime, modified basalt fiber and loess, nano-silica which is uniformly dispersed and distributed grows on the surface of the modified basalt fiber in situ, and the coating area of the nano-silica on the surface of the basalt fiber is 70-90%; the improved collapsible loess roadbed provided by the invention is prepared from the filler. The improved roadbed is high in strength, small in deformation, high in water stability and low in brittleness, and the collapsibility coefficient is remarkably reduced.
本发明公开了一种改良湿陷性黄土路基、填料、填料制备方法及路基施工方法，属于路基技术领域。本发明的改良湿陷性黄土路基填料，该填料包含石灰、改性玄武岩纤维和黄土，其中，改性玄武岩纤维的表面原位生长有均匀分散分布的纳米二氧化硅，且纳米二氧化硅在玄武岩纤维表面的包覆面积为70‑90％；本发明的改良湿陷性黄土路基，采用上述填料制备而成。本发明改良后的路基不仅强度大、变形小、水稳定性高，同时脆性较低，湿陷性系数显著减小。
