摘　　要：底基层是路面重要的承重层,在一些特殊的地质下若底基层材料选择不合理,道路面层就会出现反射断板及较严重的裂缝。结合户县新城路路基处理的工程实践,介绍了将天然砂砾石作为道路底基层时对于砂砾石质量的控制、施工工艺及施工中出现问题的解决措施,以期为今后遇到类似特殊地质道路基层的施工提供参考。The subbase is the important bearing layer of pavement. Under some special geological conditions such as the unreasonable choice of the subbase material, the road surface will have the reflective and more serious cracks. Combined with the engineering practice of road base in the new town of Hu County, this paper introduces the quality control, the construction technology and the solution of the problems in construction of sand gravel when the natural sand grave is used as the subbase of road in order to provide the reference for the construction of road base in the similar special geology in the future.
