摘要
采用逐级填充方法,通过最大密实度曲线可以确定出粗集料级配和粗细集料的填充比例,得到理想的骨架密实结构。与规范中值级配进行抗压强度、劈裂强度和缩裂性质的比较结果表明:该方法确定的混合料级配具有良好的路用性能。
The grading of coarse aggregates and the fine aggregate filling proportion were determined according to the maximum density curve by the step filling method. Then an ideal framework dense structure of cement stabilizing crushed rock was obtained. Result showed that the graded aggregates in asphalt mixture determined by this method exhibited good road performances, including compressive strength, splitting strength, and shrinkage crack, compared with those determined by the specification.
