摘要
通过对水泥稳定页岩土、二灰稳定页岩土、固化剂稳定页岩土、掺入软质集料的水泥稳定页岩土和掺入软质集料的二灰稳定页岩土基层材料进行温度收缩特性的试验研究,得出在缺乏硬质石料的地区用掺入软质集料的水泥稳定页岩土和二灰稳定页岩土比水泥类稳定和固化剂稳定页岩土具有更好的变形特性,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 temperature shrinking property of cement stabilizd shale soil;lime-flyash stabilizd shale soil;solidify agent stabilizd shale soil and lime-flyash stabilizd shale soil adding soft aggregate are researched .Finally, lime-flyash stabilizd shale soil adding soft aggregate and cement stabilizd shale soil adding soft aggregate are preference than cement stabilizd shale soil; lime-flyash stabilizd shale soil and solidify agent stabilizd shale soil in temperature shrinking property,they are used as pavement base of county road in lacking aggregate district is reasonable.
