摘　　要：通过室内试验,对4种不同沥青结合料生产的不同级配的沥青混合料进行单轴压缩动态模量试验以及车辙试验,并对不同温度下所测出的动态模量与对应沥青混合料的动稳定度结果进行分析。分析结果表明,加入添加剂的沥青混合料在动态模量提升的同时,动稳定度也有所提高,但是二者并不是线性比例关系。Through the laboratory test, the test on dynamic modulus of uniaxial compression and wheel rutting test are made for asphalt mixtures of different gradation produced by 4 kinds of different asphalt binder materials, and the analysis is made on the results of dynamic modulus tested under different temperatures and dynamic stability of corresponding asphalt mixture. The analysis results show that, the dynamic stability also improves when the dynamic modulus of asphalt mixture improves by adding additive, but not a relationship of linear proportion
