Production method of high-strength wear-resistant regenerated SMA asphalt mixture
The invention discloses a production method of a high-strength wear-resistant regenerated SMA asphalt mixture. The production method comprises the following steps: preparation of raw materials, regeneration treatment of old asphalt, preparation of regenerated crushed aggregates, preparation of asphalt mastic, preparing a regenerated SMA asphalt mixture and canning of a finished product. Accordingto the invention, the recycled old asphalt and the recycled aggregates are used as raw materials to prepare the recycled SMA asphalt mixture, so that production cost is reduced; the recycled aggregates are crushed into coarse aggregates and fine aggregates, so that all the raw materials in the SMA asphalt mixture are connected more tightly; meanwhile, the friction coefficient of the SMA asphalt mixture is increased to a certain extent through the roughness and the edges and corners of the surface; rubber powder and an anti-stripping agent are added in the production process, so that the produced SMA asphalt mixture has very good toughness and a good vibration reduction effect; and the carbon black is added in the production process to inhibit reduction of hardness during heating after theSMA asphalt mixture is paved into a pavement, and fatigue resistance and wear resistance of the SMA asphalt mixture are also improved.
本发明公开一种高强耐磨再生SMA沥青混合料生产方法，包括以下步骤：准备原料、旧沥青再生处理、再生碎骨料预处理、沥青玛蹄脂制备、再生SMA沥青混合料制备和成品罐装；本发明通过采用再生旧沥青和再生骨料作为原料进行再生SMA沥青混合料的制备，降低了生产成本，通过将再生骨料破碎为粗骨料和细骨料，使SMA沥青混合料中各原料连接更为紧密，同时通过表面的粗糙和棱角一定程度上也增加了SMA沥青混合料的摩擦系数，通过在生产过程中加入橡胶粉和抗剥落剂使生产出的SMA沥青混合料具备很好的韧性和良好的减振效果，通过在生产过程中加入炭黑抑制了SMA沥青混合料铺成路面后在升温时硬度的降低，还增加了其耐疲劳性和耐磨性。
