摘要
运用灰关联分析方法，评价表征沥青低温抗裂性能指标。结果表明沥青结合料的低温感温比与美国ＳＨＲＰ规范提出的沥青结合料低温弯曲蠕变劲度模量相关性较好，１０℃延度与美国ＳＨＲＰ规范提出的沥青结合料低温直接拉伸破坏应变相关性较好。
The paper adopts the theory of grey relation degree to evaluate the anti cracking indications of asphalt binders at low temperature,The results indicate that it has better relation degree between the temperature susceptibility ratio at low temperature and the bend creep stiffness of asphalt binders;and it has better relation degree between the ductility at 10℃ and the direct tension failure strain of asphalt binders at low temperature.
