摘　　要：通过室内试验,研究了国内外几种抗车辙剂对AC-20型沥青混合料高温稳定性、水稳定性以及低温抗裂性的影响。通过试验对比,几种抗车辙剂对沥青混合料动稳定度均有较大程度的提高,且效果优于岩沥青改性沥青。个别抗车辙剂对沥青混合料的水稳定性能有所减弱。综合试验结果确定了最佳抗车辙剂。Through laboratory experiment,the influence of several kinds of anti-rut agents at home and abroad on high temperature stability,water stability and low temperature anti-cracking performance of AC-20 type asphalt mixture is studied. Through experiment comparison,several kinds of anti-rut agents have greatly improved the dynamic stability of asphalt mixture,and the effects were superior to those of rock asphalt and modified asphalt. Individual anti-rut agent has reduced the water stability of asphalt mixture. The best anti-rut agents are determined by comprehensive experimental results.
