Process for preparing recycled asphalt mixture by using construction waste recycled aggregate
The invention discloses a process for preparing a recycled asphalt mixture by using construction waste recycled aggregate. The process comprises the following steps of: screening crushed construction waste recycled aggregate into recycled coarse aggregate and recycled fine aggregate; mechanically strengthening the recycled coarse aggregate to obtain strengthened recycled coarse aggregate, the mechanical strengthening comprising the steps of removing cement mortar wrapping the surface of the recycled coarse aggregate and polishing away edges and corners on the surface of the recycled coarse aggregate; introducing CO2 gas into the recycled fine aggregate for chemical strengthening to obtain strengthened recycled fine aggregate; and respectively doping a certain amount of the strengthened recycled coarse aggregate and the strengthened recycled fine aggregate into corresponding natural coarse aggregate and natural fine aggregate, and designing the mix proportion of the recycled asphalt mixture to prepare the recycled asphalt mixture. According to the invention, a large amount of construction waste resources generated in life can be fully utilized, the produced good recycled aggregate is doped into the asphalt mixture to prepare the recycled asphalt mixture, and the purposes of cyclic development and green development of road construction are achieved.
本发明公开了一种利用建筑垃圾再生骨料制备再生沥青混合料的工艺，包括：将破碎后的建筑垃圾再生骨料筛分为再生粗骨料和再生细骨料；对再生粗骨料进行机械强化，得到强化后的再生粗骨料，机械强化包括去除包裹在再生粗骨料表面的水泥砂浆以及打磨掉再生粗骨料表面的棱角；向再生细骨料中通入CO2气体进行化学强化，得到强化后的再生细骨料；将一定量的强化后的再生粗骨料和强化后的再生细骨料分别掺入对应的天然粗骨料和天然细骨料中后，进行再生沥青混合料的配合比设计，制备再生沥青混合料。本发明能够将生活中产生的大量建筑垃圾资源充分利用，生产成良好的再生骨料掺入沥青混合料中制得再生沥青混合料，实现公路建设循环发展、绿色发展目标。
