摘　　要：研究了回收聚乙烯蜡对SBS改性沥青和基质沥青的改性效果,比较了回收聚乙烯蜡与Sasobit对沥青的改性效果。结果表明回收聚乙烯蜡降低了沥青的高温粘度,具有很好的低温施工性,同时提高了沥青路面的高温使用性能,回收聚乙烯蜡作为有机降粘剂具有很好的应用前景。The influence of adding recycling polyethylene wax to binder of penetration grade 70 and SBS modified asphalt were investigated and the different effects of recycling polyethylene wax and SasobitFT wax on the asphalt structural performance were compared, The addition of recycling polyethylene wax decreased the viscosity of mixtures at high temperature, but increased the rutting resistance of mixtures. The results show that asphalt mixture modified by recycling polyethylene wax has fine construction performance at low temperature and the recycling polyethylene as an organic viscosity - reducer has a splendid future.
