High-elasticity modified asphalt, modified asphalt mixture and preparation method and application thereof
The invention discloses high-elasticity modified asphalt, a modified asphalt mixture as well as a preparation method and application thereof. The high-elasticity modified asphalt is prepared from the following raw material components in parts by weight: 70 to 88 parts of matrix asphalt, 10 to 16 parts of SBS (Styrene Butadiene Styrene), 2 to 4 parts of nitrile rubber, 8 to 16 parts of naphthenic oil, 1 to 3 parts of RET modifier and 0.3 to 0.6 part of anti-stripping agent. The modified asphalt mixture prepared from the high-elasticity modified asphalt disclosed by the invention has good fatigue resistance and deformation following capability, and is suitable for steel bridge deck pavement.
本发明公开了一种高弹性改性沥青、改性沥青混合料及其制备方法和应用。该高弹性改性沥青，其原料包括以下重量份的组分：基质沥青70～88份、SBS 10～16份、丁腈橡胶2～4份、环烷油8～16份、RET改性剂1～3份和抗剥落剂0.3～0.6份。用本发明的高弹性改性沥青制备的改性沥青混合料具有良好的抗疲劳性和变形追随能力，适合用于钢桥面铺装。
