Preparation process of normal-temperature large-proportion recycled asphalt mixture
The invention relates to the field of preparation of recycled asphalt, and particularly discloses a normal-temperature large-proportion recycled asphalt mixture preparation process which comprises the following steps: step 1, preparing raw materials which comprise 40-60% of waste asphalt mixture, 30-50% of new aggregate, 5-10% of mineral powder, micro-nano strengthening liquid and bio-based additive based on the total mass of the waste asphalt mixture, 30-50% of new aggregate and 5-10% of mineral powder; 2, crushing the waste asphalt mixture until the particle size is less than or equal to 30mm, and screening to remove impurities, so as to obtain the crushed and screened waste asphalt mixture; according to the invention, the waste asphalt mixture is used in a high proportion, so that the requirements on new asphalt and new aggregate are remarkably reduced, the exploitation pressure on natural resources is reduced, the accumulation and treatment cost of the waste asphalt mixture is reduced, the reutilization of the resources is realized, and good environmental protection benefits are achieved; and by introducing the micro-nano reinforcing liquid and the bio-based additive, the performance of the recycled asphalt mixture is remarkably enhanced.
本发明涉及再生沥青制备领域，具体公开了一种常温大比例再生沥青混合料制备工艺，包括以下步骤：步骤一：准备原料，包括废旧沥青混合料占总质量的40％‑60％，新集料占30％‑50％，矿粉占5％‑10％，以及微纳米强化液和生物基添加剂；步骤二：将废旧沥青混合料进行破碎至粒径小于等于30mm，并筛分去除杂质，得到破碎筛分后的废旧沥青混合料；本发明通过高比例地使用废旧沥青混合料，显著减少了新沥青和新集料的需求，降低了对自然资源的开采压力，同时减少了废旧沥青混合料的堆积和处理成本，实现了资源的再利用，具有良好的环保效益；通过微纳米强化液和生物基添加剂的引入，显著增强了再生沥青混合料的性能。
