Cold region roadbed soil curing agent
The invention relates to a road administration curing agent, in particular to a cold region roadbed soil curing agent which comprises 2%-2.5% of lignin, 14%-16% of lime powder, 20%-23% of gravel, 1%-2% of sulfonate, 5%-10% of silica fume, 30%-35% of a polyurethane adhesive, 10%-15% of epoxy resin and 6%-8% of diethylenetriamine. According to the method, after the curing agent is used in the cold region, the moisture content is remarkably lower than 24.3% and the maximum dry density after compaction is 1.423 g/cm < 3 > in pattern layer detection near the heat preservation layer, in the construction process, the moisture content below the pattern layer can be reduced only by adopting a simpler construction mode, meanwhile, the outermost layer of the roadbed is covered with the heat preservation layer for heat preservation, and therefore the heat preservation effect of the roadbed is improved. According to the present invention, the layered density can be increased while the influence of the external temperature can be reduced, the good effect can be provided at the temperature of-30 DEG C or more, and the influence caused by the frozen soil expansion can be reduced at the temperature of-80 DEG C or more;
本发明涉及路政固化剂，特别涉及一种寒区路基土固化剂，包括木质素：2％‑2.5％，石灰粉：14％‑16％，砾石：20％‑23％，磺酸盐：1％‑2％，硅灰：5％‑10％，聚氨酯粘合剂：30％‑35％，环氧树脂：10％‑15％，二乙烯三胺：6％‑8％。本发明通过采用固化剂在寒区使用后，在对保温层附近的图层检测中，含水率显著低于24.3％，击实后最大干密度为1.423g/cm3，施工流程中，仅采用更简单的施工方式即可降低图层下水分的含量，与此同时，在路基的最外层会覆盖有用于保温的保温层，能够在增加层状密度的同时，降低外部温度的影响，能够在零下30度以上具有良好效果，在零下80度以上能够降低冻土膨胀带来的影响。
