摘　　要：在不同的养生温度条件下,分别对水泥稳定碎石基层材料进行了无侧限抗压强度、劈裂强度试验、干缩试验以及温缩试验,通过比较不同养生温度条件下的试验结果,发现水泥稳定碎石基层材料的强度及收缩变形性能受施工、养护温度影响较大。研究表明:10℃养生条件,可以明显减小负温度条件下水泥稳定碎石的收缩变形;水泥稳定碎石基层在0℃～10℃条件下,施工、养生有利于提高其抗裂性能。A series of trials were done under the condition of different curing temperature,such as trials of unconfined compression strength,splitting tensile strength,dry shrinkage and temperature shrinkage of cement-stabilized macadam base course material.It is found that temperature of construction and curing has evidence influence on strength and shrinkage performance of cement-stabilized macadam base course material by comparing trial results.Result shows：Under the temperature of ten degree,shrinkage deformation of cement-stabilized macadam can be evidence decreased under negative temperature.Crack resistance of cement-stabilized macadam base course can be improved if construction and curing are conducted under the temperature range of zero to ten degree.
