摘要
采用均匀设计,研究了玄武岩纤维水泥稳定碎石的配合比;通过线性回归分析确定了水泥剂量、纤维长度、纤维剂量三因素对玄武岩纤维水泥稳定碎石7d无侧限抗压强度、7d劈裂抗拉强度及7d干缩系数影响的主次关系,根据所回归模型与相关公路规范,并结合工程实际情况,分析得出了各因素之间的最优组合。
The uniform design is applied to study the mix proportion of cement stabilized macadam reinforced with basalt fiber;some factors that affecting the 7d unconfined compressive strength, 7d splitting strength and 7d dry shrinkage such as cement dosage, basalt fiber length and basalt fiber dosage are ordered through linear regression analysis. Accord-ing to the regression model and related highway specifications, and combined with engineering practice, the best scheme is put forward.
