Recycled asphalt concrete and preparation process thereof
The invention relates to recycled asphalt concrete and a preparation process thereof, and relates to the field of building materials, and the recycled asphalt concrete is prepared from the following raw materials in parts by weight: 50-60 parts of new asphalt and 30-50 parts of reinforced aggregate, the preparation method of the reinforced aggregate comprises the following steps: uniformly stirring and mixing 20-30 parts of a new aggregate coated with a calcium oxide layer and 35-55 parts of a recycled asphalt mixed old material coated with a fly ash layer to obtain a combined body, then adding water into the combined body to react for 30-60 minutes, filtering, and drying at 40-50 DEG C to obtain the reinforced aggregate, the preparation process of the recycled asphalt concrete comprises the following steps: pouring the reinforced aggregate into new asphalt, and uniformly stirring and mixing to obtain the recycled asphalt concrete. The method has the effects of improving the cracking problem of the recycled asphalt concrete and prolonging the service life of the road.
本申请涉及一种再生沥青混凝土及其制备工艺，涉及建筑材料的领域，一种再生沥青混凝土，由包含以下重量份的原料制成：新沥青50‑60份和加强集料30‑50份；所述加强集料的制备方法为：将20‑30份包覆有氧化钙层的新集料和35‑55份包覆有粉煤灰层的再生沥青混合旧料搅拌混合均匀，得结合体，然后向结合体中加入水反应30‑60min，过滤后，在40‑50℃下烘干，得加强集料；一种再生沥青混凝土的制备工艺，将加强集料倒入新沥青中搅拌混合均匀，得再生沥青混凝土。本申请具有改善再生沥青混凝土开裂的问题，延长道路的使用寿命的效果。
