摘　　要：在缺乏石屑的地区,进行水泥稳定碎石设计时,可掺加部分细砂。通过试验研究揭示不同细砂掺量对水泥稳定碎石性能的影响规律:在一定的范围内,掺入细砂的水泥稳定碎石除了总收缩率有较大增加外(但仍满足规范要求),其它各项性能均有所提高,尤其是抗冻性和疲劳特性;采用灰色系统评价表明,采用10%细砂掺量的水泥稳定碎石将获得较好的力学性能。As making a design of cement-stabilized macadam in the area lack of stone chips, a part of fine sand could be mixed. The discipline of find sand in different proportion affecting performance of cement- stabilized macadam is disclosed through experimental study. Within certain range, other than total rate of shrinkage （however it can still meet the specified requirement ）, the performances of cement-stabilized macadam mixed with fine sand are increased, especially frostresisting and fatigue properties. The grey correlation evaluation shows that fine sand with the proportion of 10 % could contribute to good mechanical performance of cement-stabilized macadam.
