摘要研究了特立尼达湖沥青(TLA)与SBS复合改性石油沥青的性能。结果表明,TLA与SBS复配对提高沥青抗变形能力具有显著的协同效应,SBS可以抵消TLA对沥青抗裂性的部分负面影响,扩大TLAMPA的适用范围。FTIR和TG曲线表明TLA和SBS是物理混合到石油沥青中的,对石油沥青的热稳定性影响不大。TLA和SBS还具有改善沥青抗老化性能的协同效应,从而延长路面的使用寿命。
Abstract The properties of Trinidad Lake Asphalt (TLA) and SBS compound modified petroleum asphalt were investigated. Results show that the compound of TLA and SBS exhibits a remarkable combined effect on enhancing the deformation resistance of asphalt, and SBS can offset partial negative effect of TLA on the creaking resistance of asphalt, which will extend the applicable area of TLAMPA. FTIR and TG curves indicate TLA and SBS are physically mixed into petroleum asphalt and have little influence on the thermal stability. TLA and SBS also exhibit combined effect on improving anti-aging performance of asphalt, which would extend the service life of pavement.
