Manufacturing method of high-performance recycled asphalt concrete
The invention relates to the technical field of asphalt concrete, and discloses a manufacturing method of high-performance recycled asphalt concrete, which comprises the following steps: step 1, collecting materials: collecting old asphalt concrete, cleaning stains on the surface of the old asphalt concrete, and drying for later use after cleaning; 2, crushing the waste materials; step 3, material separation: the old asphalt concrete blocks are flatly laid and fed into a drying oven, the drying oven is started to melt asphalt attached to the surfaces of the old asphalt concrete blocks, and the old asphalt is separated from the concrete; step 4, classified collection: separating the old asphalt from the concrete blocks, then independently storing the old asphalt and the concrete blocks, continuously crushing the concrete blocks into 1cm < 3 >-2cm < 3 > particles, and then storing the particles; 5, separating the old asphalt, cooling the old asphalt into a semi-solid state, and fusing the semi-solid old asphalt group and the novel asphalt group according to a ratio of 1: 9 to obtain standby asphalt; and step 6, adding a fiber material into the mixture obtained in the step 5, and mixing the standby asphalt fused with the fiber material with concrete particles to obtain the recycled asphalt concrete.
本发明涉及沥青混凝土技术领域，且公开了一种高性能再生沥青混凝土的制作方法，包括以下步骤：步骤一、收集材料：将旧沥青混凝土收集，并清理旧沥青混凝土表面污渍，清洗完成后干燥备用；步骤二、破碎废料；步骤三、材料分离：旧沥青混凝土块体平铺送入烘箱，启动烘箱融化旧沥青混凝土块表面附着的沥青，将老旧沥青和混凝土分离；步骤四、分类收集：老旧沥青与混凝土块分离后单独存储，混凝土块继续打碎为1cm3‑2cm3颗粒后另存；步骤五、将老旧沥青分离后冷却半固态，半固态旧沥青团与新型沥青团以1:9的比例融合，得到备用沥青；步骤六、向步骤五中加入纤维材料，并将融合纤维材料后的备用沥青与混凝土颗粒混合得到再生沥青混凝土。
