摘要 通过对沥青混凝土车辙发生及发展的分析,车辙与沥青混凝土内部温度、材料性能、路面结构、行车荷载、行车速度有很大的关系。通过单因素分析法对各影响因子与车辙总变形建立了关系;而对于路面材料性能方面,选用三轴重复荷载试验进行了模拟,并用其结果———流变数FN来表征沥青混凝土的抗车辙性能,并建立了关系,结果表明预估精度可靠,最后运用SPSS统计软件对影响车辙总变形的多参数综合拟合,经验证明拟合结果具有较高的精度。 By analysing the occurrence and development of asphalt concrete rut,the paper discussed the relationship of rut,asphalt internal temperature,material properties,pavement structure,vehicle load and vehicle speed etc.for reference.
