水泥稳定风积砂碎石基层正交试验研究

Orthogonal experiment research on cement stabilized aeolian sand and macadam base course

笔者利用正交试验设计方法,以7d无侧限抗压强度为考核指标,在风积砂中加入水泥及碎石进行室内配合比试验研究,来考察水泥稳定风积砂碎石基层路用性能及水泥含量、碎石含量、碎石级配对路用性能的影响.试验结果表明,水泥稳定风积砂碎石做基层在公路上的应用是可行的.

By using orthogonal tests, with the 7d-unconfined compression strength as criteria, through indoor blending ratio tests about cement and macadam added to eolian sand, this paper studies the road performance of cement stabilized aeolian sand and macadam base course and analyses the effects of cement content, macadam content and macadam gradating on road performance. The results indicate that using cement stabilized aeolian sand and macadam, as base course for road is feasible.
