Extra-heavy traffic high-modulus asphalt mixture additive and preparation method thereof
The invention provides an extra-heavy traffic high-modulus asphalt mixture additive and a preparation method thereof, and the additive is prepared from the following raw materials in percentage by mass: 40-88% of polyethylene, 10-20% of calcium carbonate, 10-20% of calcium carbonate, 10-20% of calcium carbonate and 10-20% of calcium carbonate. 3%-40% of polypropylene; 5%-10% of a compatilizer; 3%-6% of a toughening agent; 0.05%-0.25% of a cross-linking agent; and 0.5%-4.5% of an anti-aging agent. The preparation method comprises the following steps: uniformly mixing the polyethylene, the polypropylene, the flexibilizer, the compatilizer, the anti-aging agent and the cross-linking agent, and then extruding and granulating by using an extruder. According to the extra-heavy traffic high-modulus asphalt mixture additive provided by the invention, the high-temperature dynamic modulus and the rutting resistance are greatly improved by means of strengthening, toughening and the like, the high-temperature dynamic modulus of the additive is greater than 4000 MPa at 45 DEG C and 10 Hz, the high-temperature dynamic modulus of the additive is greater than 1000 MPa at 45 DEG C and 0.1 Hz, and the additive is particularly suitable for long and large longitudinal slopes and other low-speed and slow-moving road sections of extra-heavy traffic with many trucks.
本发明提供一种特重交通高模量沥青混合料添加剂及其制备方法,所述添加剂以质量分数计，原料中各组分含量为，聚乙烯：40％～88％；聚丙烯：3％～40％；相容剂：5％～10％；增韧剂：3％～6％；交联剂：0.05％～0.25％；防老剂：0.5％～4.5％。制备方法为将聚乙烯、聚丙烯、增韧剂、相容剂、防老剂以及交联剂混合均匀，然后使用挤出机挤出造粒，即得。本发明提供特重交通高模量沥青混合料添加剂，通过增强、增韧等手段，大幅提高高温动态模量与抗车辙能力，其高温动态模量45℃、10Hz大于4000MPa以上，45℃、0.1Hz大于1000MPa以上，尤其适用于货车较多的特重交通的长大纵坡等速度较低及缓行路段。
