摘要
以OGFC-10级配为研究对象,通过正交试验方法分析了9.5 mm、4.75 mm和2.36 mm三个关键筛孔通过质量百分率对OGFC抗剪强度的影响。研究表明:4.75 mm和2.36 mm通过百分率对OGFC有显著性的影响,而9.5 mm通过率没有显著性的影响。通过进一步分析可以得出:对于最大公称粒径相同的级配,可以通过空隙率近似预估其抗剪强度。
Based on OGFC10,the impact of 2.36mm,4.75mm and 9.5mm passing percentage on shear strength of mixtures is studied by orthogonal test method.The results show that:the impact of 4.75mm and 2.36mm passing percentage is significant,while the impact of 9.5mm passing percentage wasn't statistically significant.Further analysis shows that the shear strength of mixtures can be predicted by their voids for the mixtures which have the same nominal maximum size.
