摘　　要：本研究成型了4种不同类型的高粘改性沥青,对其流变性能和高温性能进行了评价。研究表明:4种改性剂均可提高基质沥青的粘弹性和高温性能,但是影响程度不同。F-SBS高粘沥青粘度最大,具有优异的高温抗变形能力,最适合用于超薄磨耗层,但是在施工时需要对其流动性进行改善;TPS高黏沥青适合用于超薄磨耗层,但是其黏度和高温性能略逊于F-SBS高黏沥青;HVA高黏沥青与LY高黏沥青的流动性较大,但是其黏度较小,高温抗变形能力较差,在超薄磨耗层中适用性较差。To assess the rheological and high-temperature properties of diverse high-viscosity asphalts,and their suitability for ultra-thin wear layers,this study examines four different types of high-viscosity asphalts.The results indicate that all four modifiers enhance the viscoelastic and high-temperature properties of the base asphalt,while the extent of this impact varies.F-SBS has the highest viscosity and excellent high-temperature deformation resistance.It is most suitable for ultra-thin wear layers,but its fluidity needs to be improved.TPS is suitable for ultra-thin wear layers,but its viscosity and high-temperature properties are slightly worse than those of F-SBS.Both HVA and LY present superior fluidity but lack the requisite viscosity and high-temperature deformation resistance,rendering them ill-suited for application in ultra-thin wear layers.
