摘要： 通过室内试验,研究了不同级配类型、油石比、试验温度下再生沥青混合料的抗车辙能力.试验结果表明,再生料的动稳定度要高于普通沥青混合料,不同的级配类型高出的幅度不同.油石比、温度的变化对再生料动稳定度影响很大,前者在一定范围内呈现反比关系,后者符合指数函数关系.根据大量的室内试验结果提出了动稳定度指标的建议值.得出的结论对沥青路面废料的再生利用具有一定的指导意义.

Abstract: Lots of lab tests were done to investigate the rut resistance of recycled asphalt mixture under conditions of different grading types, tar-rubble ratios and testing temperatures. Testing result indicated that the dynamic stability of recycled mixture is higher than that of common asphalt mixture, to which the different grading types offer differently. The influences of tar-rubble ratio and temperature change on the dynamic stability is very obvious, where the ratio is in inverse proportion to the stability and the temperature change is in an exponential functional relation with the stability. A value of dynamic stability is therefore recommended on the basis of testing results. The conclusion drawn from the investigation will offer guidance to the recycling of waste asphalt pavement materials.
