Road roadbed material prepared from mine waste residues and preparation method of road roadbed material
The invention discloses a road roadbed material prepared from mine waste residues, which is prepared by the following steps: mixing crushed coal mine waste residues, metal mine waste residues, bentonite, cement, lime, waste tire rubber particles, polymer fibers and a buffer agent, fully stirring to uniformly distribute the components to obtain a mixture, adding an acidic regulator or an alkaline regulator into the mixture, and uniformly mixing to obtain the road roadbed material. The pH value of the mixture is adjusted to 6-8, the adjusted mixture is compacted through a layered compaction method, the thickness of each layer is about 20-30 cm, and the mining area waste residue highway subgrade is formed. According to the invention, the coal mine waste residues, the metal mine waste residues and the waste tire rubber particles are mixed, the mixture is used as an infiltration material to improve bentonite, and then the mixture is mixed with cement, lime and the like to prepare the highway subgrade material, so that a new way is effectively developed for treating industrial wastes, and resource reutilization is realized. Meanwhile, the shear strength of the improved highway subgrade material is increased, and a small compression coefficient and low permeability are kept.
本发明公开一种矿区废渣制备的公路用路基材料，将破碎后的煤矿废渣、金属矿废渣、膨润土与水泥、石灰、废旧轮胎橡胶颗粒、聚合物纤维和缓冲剂混合进行充分搅拌，使各组分均匀分布，得到混合物，在混合物中添加酸性调节剂或碱性调节剂，调整混合物的pH值至6‑8，采用分层压实的方法，将调整好的混合物进行压实，每层厚度约为20‑30cm，形成矿区废渣公路路基。本发明将煤矿废渣、金属矿废渣和废旧轮胎橡胶颗粒混合，将其作为渗入料来改良膨润土，再与水泥和石灰等混合制备成公路路基材料，有效的为处理工业废弃物开拓了新的途径，实现资源再利用。同时改良后的公路路基材料抗剪强度增大且保持较小的压缩系数和低渗透性。
