| 摘 要： | 分别采用TPS和SBS制备了高粘度改性沥青和普通SBS改性沥青。研究了两种改性沥青在旋转薄膜烘箱(RTFOT)、压力老化箱(PAV)和紫外光老化前后物理性能的变化。结果表明:TPS改性沥青的抗短期热氧老化和长期热氧老化性能优于SBS改性沥青,同时,TPS改性沥青具有良好的抗紫外光氧老化性能。

| Abstract: | TPS and SBS were employed to prepare high viscosity modified asphalt and common modified asphalt,respectively.Two kinds of modified asphalt were aged by means of the rolling thin film oven test(RTFOT),pressure ageing vessel(PAV) and ultraviolet(UV) photooxidation ageing.The relative properties of modified asphalt were investigated before and after ageing.The results indicated that TPS modified asphalt had better ageing resistance compared with common SBS modified asphalt after RTFOT and PAV ageing.Besides,T... |
