Ardealite road base material and preparation method thereof

The invention discloses an ardealite road base material and a preparation method thereof. The ardealite road base material is prepared from the following raw materials in parts by weight: 15-20 parts of flotation ardealite, 80-85 parts of gravel aggregate, 5-7 parts of a curing agent, 1-2 parts of a curing accelerator, 0.4-1 part of an adhesive and 0.3-0.6 part of a water reducing agent. The curing agent is composed of cement, fly ash and quick lime; the curing accelerator is composed of triethanolamine and water glass. Under the condition of ensuring no pollution to the environment, the consumption of the stockpiled phosphogypsum is greatly increased, and the strength and stability of the road base are improved. 本发明公开了一种磷石膏公路基层材料及其制备方法，由以下重量份的原料组成：浮选磷石膏15～20份，碎石集料80～85份，固化剂5～7份，固化促进剂1～2份，胶粘剂0.4～1份，减水剂0.3～0.6份；所述固化剂由水泥、粉煤灰、生石灰组成；所述固化促进剂由三乙醇胺和水玻璃组成。本发明在保证对环境无污染的情况下，大幅度提高了对堆存磷石膏的消耗，且提高了公路基层的强度和稳定性。
