摘　　要：采用A级70号、A级70号+抗车辙剂及SBS改性沥青作为胶结料拌制沥青混合料,分别对三种沥青混合料的高温稳定性、抗水损害能力及低温抗裂性能等路用性能进行了室内试验研究。试验结果表明掺加抗车辙剂的沥青混合料高温稳定性得到很大程度的提高,抗水损害能力没有显著变化,低温抗裂性略有降低。Using grade A 70 asphalt, SBS modified asphalt and anti - rutting agent, a series of mixture experiments were carried on to evaluate pavement performance of anti - rutting agent. The performances of three asphalt mixtures were tested, including high temperature stability, moisture damage stability, low tem- perature crack resistance. The results showed that the addition of anti - rutting agent could enhance the high temperature stability and moisture stability of asphalt mixture, but had a negative effect on low temperature crack resistance.
