Preparation method of recycled asphalt concrete
The invention relates to the technical field of road construction materials, in particular to a recycled asphalt concrete preparation method which comprises the following steps: S1, separating recycled asphalt aggregate and recycled powder through a screening technology; s2, forming modified asphalt; s3, carrying out drying treatment on the recycled asphalt aggregate and the recycled powder at high temperature; s4, mixing and stirring the treated regenerated asphalt aggregate and regenerated powder with fresh asphalt aggregate, fresh powder and modified asphalt according to a certain proportion; s5, carrying out shearing and homogenizing treatment on the mixture A; s6, the treated mixture A is laid and compacted; and S7, the concrete is cooled under the natural condition, and then wet curing treatment is conducted. According to the invention, by optimizing the treatment of the recycled material and the proportion of the mixture, the performance of the recycled asphalt concrete is remarkably improved, meanwhile, the cost is reduced, the environmental influence is reduced, and an economical, efficient and environment-friendly new material solution is provided for road construction.
本发明涉及道路建设材料技术领域，具体涉及一种再生沥青混凝土制备方法，包括以下步骤：S1：通过筛分技术分离出再生沥青骨料和再生粉料；S2：形成改性沥青；S3：将再生沥青骨料和再生粉料在高温下进行干燥处理；S4：将处理后的再生沥青骨料和再生粉料与新鲜沥青骨料、新鲜粉料以及改性沥青按一定比例混合并搅拌；S5：对混合料A进行剪切均质处理；S6：将处理后的混合料A在进行铺设和压实；S7：混凝土在自然条件下冷却，随后进行湿养护处理。本发明，通过优化再生材料的处理和混合料配比，显著提升了再生沥青混凝土的性能，同时实现了成本降低和环境影响减轻，为道路建设提供了一种经济高效且环境友好的新材料解决方案。
