摘　　要：通过试验分析了集料级配类型、试件尺寸、水泥剂量、水泥品种、集料针片状颗粒含量等对水泥稳定碎石无侧限抗压强度的影响规律及分析了不同延迟时间对水泥稳定碎石不同龄期无侧限抗压强度和劈裂强度的影响,从而为强度的合理限值提供了依据.The influence rules of some factors, such as type of gradation of aggregate, dimension of specimen, dosage of cement, type of cement and content of needle and piece granule of aggregate on unconfined compressive strength of cement-stabilized macadam were studied. The influence of forming retarded time on unconfined compressive strength and splitting tensile strength for different ages are also analyzed. The test results provide the references for reasonable bounds of strength.

关 键 词：水泥稳定碎石 集料级配类型 延迟时间 无侧限抗压强度 劈裂强度
