摘　　要：通过对水泥稳定红砂土、石灰粉煤灰稳定红砂土、固化剂稳定红砂土、掺入软质集料的水泥稳定红砂土和掺入软质集料的石灰粉煤灰稳定红砂土基层材料进行干燥收缩特性的试验研究,得出掺入软质集料的水泥稳定红砂土和掺入软质集料的石灰粉煤灰稳定红砂土比水泥稳定红砂土和固化剂稳定红砂土具有更小的干缩系数,作为缺乏硬质石料地区的县乡道路的路面基层材料是可行的,有较好的应用推广价值.In this paper, the dry shrinking property of cement stabilized red sand soil; lime-fly ash stabilized red sand soil; solidify agent stabilized red sand soil and lime-fly ash stabilized red sand soil adding soft aggregate are reseated, finally, lime-fly ash stabilized red sand soil adding soft aggregate and cement stabilized red sand soil adding soft aggregate are preference than cement stabilized red sand soil; lime-fly ash stabilized red sand soil and solidify agent stabilized red sand soil in dry shrinking property, which are used as pavement base Of county road in lacking aggregate district is reasonable, it has a good application value.
