水泥稳定碎石劈裂强度影响因素研究

Research on influencing factors of the splitting strength of cement stabilized macadam

从养生龄期、水泥剂量、集料的级配类型和试件成型方式四个方面,对水泥稳定碎石混合料劈裂强度进行分析与研究,在此基础上定量分析劈裂强度与四个主要影响因素之间的关系,对水泥稳定碎石基层劈裂强度与影响因素之间的关系进行了拟合,建立了数值模型。

In this paper,the splitting strength of cement stabilized macadam mixture was analyzed and studied from four main aspects of this mixture： health age,cement dosage,gradation type of aggregate and specimen forming method. Based on this, the relationship between the splitting strength and the four main influencing factors was quantitatively analyzed. The relationship between the splitting strength and the influencing factors of the cement stabilized macadam base was fitted to establish a numerical model for the reference of pavement structure design and performance prediction.
