研究表明，掺加二灰后级配碎石混合料的性能显著提高，特别是二灰的填充系数为0。
The results show that the performances of graded gravel mixture are improved significantly after being treated with cement and lime, especially when fill factor is 0.
通过正交试验，找到二灰碎石各种材料的用量比例，主要是二灰内比、碎石比例和级配、水泥掺量等与结构强度、横缝出现情况的关系。
The mixture ratios mainly including the proportion of Lime and Fly-ash, aggregate and grading collocation and the cement parameter are found out through orthogonal experiment.
间断级配时间断区段的粒径越大，二灰碎石的强度越高。
The bigger the size of intermittent division in discontinuous gradation is adopted, the higher the strength becomes.
