Cement consolidation sandy soil for roadbed filling construction
The invention relates to cement consolidated sandy soil for roadbed filling construction, the main material is sandy soil, the water content of the sandy soil is 9%-10%, and 4% of Po42.5 retarded cement and 0.015% of a middle road No.1 soil stabilizer are added by weight and uniformly mixed. The method is used for roadbed base layer and subbase layer filling construction, road building materials can be greatly saved, the construction efficiency is improved, the construction cost is reduced, cracks of the base layer and the subbase layer are controlled to a certain degree, and the durability of the road surface is improved.
本发明涉及一种用于路基填筑施工的水泥固结砂性土，主料为砂性土，所述砂性土含水量为9％‑10％，并按重量百分比添加4％的Po42.5缓凝水泥、0.015％的中路1号土壤固化剂拌匀。本发明用于路基基层、底基层填筑施工，可大量节省筑路材料，提高施工效率，降低施工成本，且在一定程度上控制了基层、底基层裂缝的产生，提高了路面的耐久性。
