摘　　要：根据砂性粉土与粘性土的水泥石灰土稳定碎石室内试验结果与路用效果 ,分析影响两类半刚性材料强度、水稳性的主次因素 ,探讨强度形成机理 ,这两类半刚性材料强度影响最显著的因素是碎石用量 ,掺粘性土时 ,集料级配比水泥用量影响大 ;掺粉性土时 ,水泥用量比集料级配影响大 ,初期强度受误差干扰较大 ,<0According to the test indoors and the effect in highway use of sand silt soil and clay soil′s stabilized aggregate by cement lime and soil, the primary and second factors influencing two kinds of semi?rigid material′s strength water stabilization are discussed in this paper.The factor influencing two kinds of semi?rigid material′s strength most is aggregate content Adding in clay soil, aggregate gradation has more effect than the content of cement; Adding in silt soil, the result is adverse And the early strength is easy to be influenced by errors In the gradated aggregate, the fine sorted material whose diameter is smaller than 0 3mm should be reduced
