Production method of self-healing recycled asphalt mixture
The invention discloses a production method of a self-healing recycled asphalt mixture. The production method comprises the following steps: preparing materials, recycling and cleaning an asphalt treatment material, preparing recycled asphalt, preparing a new aggregate, preparing modified asphalt, preparing a mixture, periodically heating and finishing the preparation. The method comprises the following steps: firstly, cleaning and inspecting a recycled asphalt treatment material; screening clay and dust to avoid the weakening of the adhesion between asphalt and a coarse aggregate; remaining an old asphalt material with the particle size of 0-10mm after screening, wherein the old asphalt material contains much asphalt, when the temperature is high in summer, the adhesion is realized, and quality is ensured; adopting a specially-made regenerant to activate the old asphalt material, so that effective adsorption and resistance on ultraviolet ray are achieved, the aging speed of asphalt isreduced; at the same time, adding niobium carbide, calcium stearate and a fiber stabilizer so as to make the interior of a finished product tighter, enhance the toughness, improve the durability of the asphalt and avoid cracking, and the effect of the magnetic powder is matched so as to make the asphalt structures have the adsorption force so as to make the crack self-healing.
本发明公开一种自愈式再生沥青混合料生产方法，包括以下步骤：准备材料、回收沥青处理料清检、制备再生沥青、制备新集料、制备改性沥青、制备混合料、周期加热和制备完成；本发明先对回收沥青处理料进行清检，筛除粘土、粉尘，避免消弱沥青与粗骨料的粘附性，并留下筛分后0‑10毫米的沥青旧料，这种沥青旧料含沥青多，夏季气温高时具有粘附性，保证质量，且本发明通过特制的再生剂，激活沥青旧料，能有效吸收抵抗紫外线，降低沥青的老化速度，同时，加入碳化铌、硬脂酸钙和纤维稳定剂，使成品内部更加紧密，增强韧性，提高沥青的耐久性能，避免开裂，另外，配合磁粉的作用，使得沥青结构相互之间具有吸附力，使得裂缝自愈。
