Preparation and Properties of Ageing Resistant Asphalt Binder with Various Anti-Ageing Additives


Article Preview

The modified asphalt binders with various anti-ageing additives, including ultraviolet (UV) absorber, antioxidant and combination of them, were prepared, and the effects of UV absorber contents, antioxidant contents and combination of UV absorber and antioxidant on physical properties and ageing characteristics of the asphalt binder were investigated. Results show that the ductility of asphalt binder increases whereas the softening point and viscosity decrease with addition of anti-ageing additives. UV absorbers and antioxidants exhibit different influences on the ageing properties of asphalt binder. The thermal- and photo-oxidative ageing performance of asphalt binder can be simultaneously improved by the compound modification with UV absorber and antioxidant. The combination of UV326 and antioxidant 1010 shows synergistic effect in preventing the asphalt binder from thermal- and photo-oxidative ageing, which contributes to excellent ageing resistance of modified asphalt binder.
