一种高粘复合改性沥青及其制备方法
摘要：
本发明涉及一种高粘复合改性沥青，包含基质沥青、相溶剂、聚合物、树脂、橡胶粉和稳定剂，其质量比为100：2~6：5~7：1~3：3~6：0.05~0.2。其制备方法为：基质沥青溶解后与相溶剂混合，再通过高速剪切法依次加入聚合物、树脂、橡胶粉和稳定剂。本发明设计合理，性能优选，使改性沥青的粘度和弹性得到极大的提高。并且，具备较高的耐久性、粘附性、抗剥落性、抗飞散性以及良好的裹附性能力，使施工更加方便，为道路施工质量的提高创造有利的条件。
摘要（英）：

The invention relates to high-viscosity composite modified asphalt which comprises matrix asphalt, compatilizer, polymer, resin, rubber powder and stabilizer according to a mass ratio of 100:2-6:5-7:1-3:3-6:0.05-0.2. A preparation method includes: dissolving the matrix asphalt, and mixing with the compatilizer; sequentially adding the polymer, the resin, the rubber powder and the stabilizer through a high-speed shearing method. The high-viscosity composite modified asphalt is reasonable in design and optimal in performance, and viscosity and elasticity of the modified asphalt are greatly improved. The high-viscosity composite modified asphalt has high durability, adhesiveness, anti-stripping performance, resistance to flying dispersion and wrapping performance and brings more convenience to construction, and a favorable condition is created for improving road construction quality.
