摘要
沥青混合料低温性能的影响因素较多。文章通过低温弯曲试验作为评价沥青混合料低温性能的技术方法,应用灰色关联理论对沥青混合料中不同筛孔集料通过率、油石比及空隙率对沥青混合料低温性能的影响程度进行分析。研究表明:灰色关联理论可以作为分析方法评价不同因素与沥青混合料低温性能的关联度,其中沥青混合料的油石比与筛孔尺寸为2.36 mm时集料的通过率对沥青混合料的低温性能的影响最大。
There are many factors influence the low temperature performance of asphalt mixture. In this paper, through the low temperature bending test as evaluation method of low temperature performance of asphalt mixture, apply the grey relation the- ory to analyze the incidence of the different mesh aggregate pass rate, asphalt - aggregate ratio and porosity on the low tempera- ture properties of asphalt mixture. Study shows that the grey relation theory can be used as a method to evaluate the correlation of different factor and low temperature performance of asphalt mixture, which the asphalt - aggregate ratio and the passing rate of mesh size of 2.36 mm aggregate has the largest influence on low temperature performance of asphalt mixture.
