Construction waste improved expansive soil roadbed structure and construction method thereof
The invention relates to a construction waste improved expansive soil roadbed structure and a construction method thereof. The bottommost layer of the structure is a gravel soil cushion layer, construction waste improved soil filler is arranged above the gravel soil cushion layer, edge covering clay is arranged on the two sides of the construction waste improved soil filler, and anti-seepage geotechnical cloth is arranged above the construction waste improved soil filler and the edge covering clay to serve as a top sealing layer. According to the physical improvement method for doping the construction waste into the expansive soil, on one hand, the expansive soil roadbed expansibility can be reduced, and on the other hand, the roadbed strength and water permeability can be improved, so that the moisture content distribution in the roadbed is more balanced, the engineering discard is reduced, the land is saved, the engineering cost is reduced, and the environmental protection is facilitated.
本发明涉及建筑垃圾改良膨胀土路基结构及其施工方法，所述结构最底层为碎石土垫层，碎石土垫层上方为建筑垃圾改良土填料，建筑垃圾改良土填料两侧设置包边粘土，建筑垃圾改良土填料和包边粘土上方设置防渗土工布作为顶封层。本发明将建筑垃圾掺入到膨胀土中的物理改良法一方面可降低膨胀土路基胀缩性，另一方面也可提高路基强度及其透水性，使路基内部含水率分布更加均衡，减少了工程弃方，节约了土地，降低了工程造价，有利于环境保护。
