摘　　要：研究选择推荐级配范围内的偏细、偏粗和接近中值的三种级配,旨在通过室内试验,对比分析不同级配微表处混合料的各项性能,最终选择施工性和路用性均为最优的级配,为微表处级配的选择提供参考,具有一定的工程实用意义。This paper chose three standard recommended gradations, which were fine, coarse and close to the median. Through indoor test, various performances of micro - surfacing mixture under different gradation were compared. The optimal gradation with constructing and paving were chose. The test provided the reference for the design of micro - surfacing mixture and had a certain practical significance.
