| 摘 要： | 针对高速公路沥青路面日益严重的车辙病害进行调查,选择代表性路段钻芯取样,分析路面车辙变形分布特征以及混合料密度和沥青含量变化规律,研究混合料空隙率、级配指数及车辙变形率与路面车辙深度的关系,并采用灰色理论对影响混合料抗车辙性能的因素进行灰关联分析。结果表明:中面层对路面车辙贡献率最大,伴随着车辙变形存在混合料进一步压密、沥青流动迁移现象,在空隙率、级配指数、车辙变形率、中面层4.75 mm通过率和粉胶比五个因素中,车辙变形率与车辙深度有最大的灰色关联度,对车辙深度的影响最为显著,可充分体现沥青混合料的抗车辙性能。

| Abstract: | Through investigation on increasingly serious rut diseases on highway asphalt pavement,the distribution of rutting deformation and the changes of mixture density and asphalt content are separately analyzed based on core boring sample of the typical section to study the influence of mixture void ratio,graduation index and rutting deformation rate on rut depth,and analyze the correlation of influencing factors of rut resistance using grey theory.The result shows that middle layer plays the most important role... |
