【摘要】 介绍了均匀设计法在开级配沥青磨耗层混合料级配设计中的应用,按5因子5水平进行试验安排,对试验数据进行回归分析,得出了混合料的空隙率和级配之间的关系,并验证了所得关系的正确性。对比了正交设计与均匀设计的不同,与正交设计相比,均匀设计法只要相对较少的试验就能达到相近的结果。均匀设计法对混合料设计,尤其是大孔隙的沥青混合料设计具有参考价值。更多还原

【Abstract】 The application of the equality design method in open graded friction course, and five genes and five levels are used to arrange the examination. By regressing these data the connection between interspace and the composition of aggregate is obtained. By comparing the design of plumb intersect and the equality, it is found that the equality design only needs fewer examinations to get the close result.The design of equality is useful for the mix with large interstice.更多还原
