摘要
文章应用灰色关联度分析理论,分别从胶结料和级配、油石比及空隙率两个角度对橡胶沥青混合料高温性能影响因素进行敏感性分析,找出评价橡胶沥青混合料高温性能的主要指标,为高温地区选择橡胶沥青混合料提供参考。研究结果表明,胶结料中的橡胶沥青的177℃粘度与级配中的9.5mm筛孔通过率和车辙试验的动稳定度的关联程度最好,与实际情况基本吻合,说明灰色关联度分析方法是一种简单有效的分析橡胶沥青混合料高温性能影响因素的方法。
By using the gray correlation analysis theory,this article conducted the sensitivity analysis on high-temperature performance influencing factors of rubber asphalt mixtures respectively from the perspectives of binder material and grading as well as bitumen aggregate ratio and porosity ratio,and identified the main indicators to evaluate the high temperature properties of rubber asphalt mixtures,thereby providing the ref-erence for selecting the rubber asphalt mixtures in high temperature areas.The study results showed that the 177 ℃viscosity of rubber cement in binder material and the 9.5mm sieve through rate in the grading has the best correlation with the dynamic stability of rutting test,which is consistent with the actual situation,indi-cating that the gray correlation analysis is a simple and effective method to analyze the high temperature performance influencing factors of rubber asphalt mixtures.
