Resource utilization method of asphalt waste powder in road subgrade paving
The invention relates to a resource utilization method of asphalt waste powder in road roadbed paving, and belongs to the technical field of waste recycling. According to the method, the asphalt waste powder and the slag or the mixture of the slag and the fly ash are uniformly placed, paving is performed after manual bag breaking, and the mixture and the soil are uniformly mixed by using a road mixer. The alkali activator is filled with the rubber pipe, the opening end is wrapped with the polyethylene plastic, the polyethylene plastic is heated after wrapping is completed, the polyethylene plastic is melted and tightly wraps the rubber pipe, and liquid leakage is avoided. And according to the calculated putting interval, point positions are drawn with lime in advance, then the rubber pipes are put with a traffic cone placing device, and after putting is completed, a layer of soil is laid on the curing agent. After the operation is completed, a road roller is used for rolling the rubber pipe to enable the alkali activator to flow out, the alkali activator and the soil are subjected to chemical reaction through the seepage effect, gelling substances are generated to fill pores between the soil bodies, the mechanical property of the soil bodies is improved, and therefore the purpose of improving the soil bodies is achieved.
本发明涉及一种沥青废粉在道路路基铺筑中的资源化利用方法，属于废弃物回收利用技术领域。本发明沥青废粉与矿渣或矿渣和粉煤灰的混合料均匀摆放，人工破袋后进行摊铺，使用路拌机将混合料与土壤均匀混合。采用橡胶管将碱激发剂进行灌装，开口端采用聚乙烯塑料进行包裹，包裹完毕对聚乙烯塑料进行加热使其熔化紧密包覆橡胶管，避免液体渗漏。根据计算得到投放间隔，提前用石灰画好点位，然后用交通锥摆放装置对橡胶管进行投放，投放完成后在固化剂上铺设一层土壤。操作完成后使用压路机对橡胶管进行碾压使碱激发剂流淌出来，通过渗流作用与土壤发生化学反应，产生胶凝物质，填充土体间的孔隙，提高土体的力学性能，从而实现了改良土体的目的。
