High-stability roadbed filler and preparation method thereof
The invention relates to the technical field of geotechnical engineering, and particularly discloses a high-stability roadbed filler and a preparation method thereof. The roadbed filler comprises the following raw materials by weight: 20 to 30 parts of gravelly soil, 10 to 20 parts of limestone, 40 to 55 parts of fly ash, 10 to 20 parts of yellow stone powder, 4 to 6 parts of an anti-freezing agent, 2 to 4 parts of a reinforcing agent, 0.8 to 1.5 parts of calcium carbonate, 1 to 2 parts of potassium carbonate, and 1 to 2 parts of phosphogypsum, wherein the anti-freezing agent comprises at least one selected from fish collagen powder and glucose. The preparation method of the roadbed filler comprises the following steps: uniformly mixing the gravelly soil, the limestone and the fly ash, adding the yellow stone powder and the phosphogypsum, and conducting uniform mixing to obtain a first mixture; uniformly mixing the first mixture with calcium carbonate and potassium carbonate, then jointly mixing the obtained mixture with the anti-freezing agent and the reinforcing agent; and conducting uniform mixing to obtain the roadbed filler. The roadbed filler disclosed by the invention has the advantage of good anti-freezing property.
本申请涉及岩土工程技术领域，具体公开了一种高稳定性路基填料及其制备方法，该路基填料包括以下重量份的原料：碎石土20‑30份；石灰石10‑20份；粉煤灰40‑55份；黄石粉10‑20份；防冻剂4‑6份；增强剂2‑4份；碳酸钙0.8‑1.5份；碳酸钾1‑2份；磷石膏1‑2份；防冻剂包括鱼胶原蛋白粉、葡萄糖中的至少一种；该路基填料的制备方法为：将碎石土、石灰石、粉煤灰混合，混合均匀后加入黄石粉和磷石膏混合均匀，得到第一混合物；将第一混合物与碳酸钙、碳酸钾混合，混合均匀后与防冻剂、增强剂共同混合，混合均匀后得到路基填料；本申请中的路基填料具有防冻性好的优点。
