摘　　要：为研究不同水泥掺量材料路基强度大小的问题,采用抚顺宝上线与新民叶苗线的两段试验路进行CBR值测试的方法,分别采用不添加水泥的级配碎石、质量分数3%低水泥剂量级配碎石、质量分数4%水泥含量的水泥稳定碎石3种不同水泥掺量的上基层分别进行现场CBR试验和室内CBR试验.研究结果表明,室内外相同材料的CBR值相差很多,不同水泥掺质量的CBR值与水泥含量有关.By selecting two test roads to do the CBR experiment, one is Bao Shang line in Fu Shun, another one is Ye Miao line in Xin Min, this paper studied the strength of the subgrade under the influence of different dosage of cement. Three different subgrades, which include no added cement graded gravel, 3% low doses of graded crushed stone cement, and 4 % cement content of cement stabilized macadam, were adopted to conduct CBR test both indoor and outdoor respectively. Through the analysis of test data comparison, the same material of the CBR value differs a lot indoor and outdoor, and different cement dosage influences on CBR value.
