摘要:
为增强SBS改性沥青的储存稳定性及路用性能,将一种廉价且性能优异的石油裂解副产品——C9石油树脂与SBS改性剂复合制备高性能的改性沥青。探究不同用量(0%、2%、4%、6%、8%)的C9石油树脂与SBS改性剂对沥青进行复合改性时,C9石油树脂对复合改性沥青的物理性能、储存稳定性、高温性能、低温性能和疲劳性能的影响。结果表明:C9石油树脂的加入,降低了软化点差ΔTR&B和流变性能主曲线的间距,提高了改性沥青的储存稳定性;由于其高软化点等特性,C9石油树脂/SBS改性沥青具有优异的高温抗变形能力,加入C9石油树脂比未加入时的不可恢复蠕变柔量明显减小;适量的C9石油树脂有助于提高改性沥青的低温抗裂性和抗疲劳性能,但由于C9石油树脂的低温脆性,用量不宜超过8%。适量添加C9石油树脂,对SBS改性沥青的储存稳定性、高温抗变形能力、低温抗裂性以及抗疲劳性能具有明显的增强效果。
Abstract:
In order to enhance the storage stability and road performance of SBS modified asphalt, C9 petroleum resin, a cheap and excellent by-product of petroleum cracking, was compounded with SBS modifier to prepare high-performance modified asphalt. The effects of C9 petroleum resin with different dosage on the physical properties, storage stability, high temperature performance, low temperature performance and fatigue performance of the composite modified asphalt were investigated. It was found that the addition of C9 petroleum resin could reduced the softening point difference ΔTR&B and the distance between the main curves of rheological properties, improve the storage stability of modified asphalt. Due to its high softening point, the asphalt modified by C9 petroleum resin and SBS had excellent high temperature deformation resistance. Under the same pressure and temperature, the Jnr of the modified asphalt was significantly reduced than that without C9 petroleum resin. Proper amount of C9 petroleum resin was helpful to improve the low temperature crack resistance and fatigue resistance of modified asphalt. However, owing to the brittleness of C9 petroleum resin at low temperature, its dosage should 6%. The storage stability, high temperature deformation resistance, low temperature crack resistance and fatigue resistance of SBS modified asphalt were significantly enhanced by adding C9 petroleum resin.
