摘要
通过对不同级配的SMA混合料水稳定性数据进行相关性分析,可以得出结论:空隙率与水稳定性指标之间存在显著的线性相关性,相关系数高达0.98以上。这表明空隙率的变化对SMA混合料的水稳定性有显著影响。
Through the pertinency analysis on water stability data of different gradation SMA mixture,the conclusion that there is distinct linear dependence relation between voidage and water stability is deduced,and the correlation coefficient is above 0.98.It indicates that the change of voidage has great influence on the water stability of SMA mixture.
