摘要
通过查阅国内外资料和进行大量室内试验 ,确定了级配 型沥青碎石和级配 型水泥碎石两种透水基层材料的配合比。并通过自制的沥青处治碎石渗透系数测试仪和水泥处治碎石渗透系数测试仪 ,分别测定了上述两种透水基层材料的渗透系数。
According to the documents and results of indoor experiments,this paper recommended proportioning of two kinds of permeable base materials which are composed of asphalt-aggregate of grading type Ⅱ and cement-aggregate of grading type Ⅵ respectively. By using the instruments to test permeability coefficient of asphalt-aggregate and cement-aggregate in laboratory,the permeability coefficient of the two kinds of permeable base materials were measured.
