Heavy-load-resistant asphalt pavement modifier as well as preparation method and application thereof
The invention discloses an anti-heavy-load asphalt pavement modifier as well as a preparation method and application thereof. The anti-heavy-load asphalt pavement modifier is prepared from the following raw materials in parts by weight: 100 parts of a polyamide reclaimed material, 5-25 parts of a glycidyl methacrylate copolymer compatilizer, 5-20 parts of waste tire rubber powder, 1-8 parts of a lubricant, 1-5 parts of a silane coupling agent, 1-5 parts of an acid acceptor and 0.1-2 parts of an antioxidant. The heavy-load-resistant asphalt pavement modifier disclosed by the embodiment of the invention has ultrahigh strength and toughness, and after the heavy-load-resistant asphalt pavement modifier is added into an asphalt mixture, not only is the shear strength of the asphalt mixture at high temperature greatly improved, but also the water damage resistance and the fatigue resistance of the asphalt mixture can be obviously improved; the method is of great significance to prevention and treatment of asphalt pavement diseases in high-temperature and extreme load environments.
本发明公开一种抗重载沥青路面改性剂、制备方法及应用，包括按如下重量份数计的原料：聚酰胺回收料100份、甲基丙烯酸缩水甘油酯共聚物相容剂5～25份、废轮胎胶粉5～20份、润滑剂1～8份、硅烷偶联剂1～5份，吸酸剂1～5份，抗氧剂0.1～2份。本发明实施例的抗重载沥青路面改性剂具有超高的强度和韧性，加入到沥青混合料中，不仅大幅提高沥青混合料在高温下的抗剪强度，还能明显改善沥青混合料的抗水损坏和抗疲劳性能，对高温和极端荷载环境下的沥青路面病害防治与处治具有重要意义。
