高黏改性沥青制备及高温流变性能
Preparation and High Temperature Rheological Properties of High Viscosity Asphalt
摘要
Abstract
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.关键词
