Modified ardealite semi-rigid base material for highway in seasonal frozen earth region and preparation method of modified ardealite semi-rigid base material
The invention discloses a modified ardealite semi-rigid base material for roads in seasonal frozen earth areas and a preparation method thereof, the modified ardealite semi-rigid base material is prepared from ardealite, lime cement and a proper amount of water, based on the ardealite, the mixing amount of the lime is 1-10%, the mixing amount of the cement is 1-10%, the mixing amount of the lime is equal to 100% * the weight of the lime/the weight of the ardealite, and the mixing amount of the cement is equal to 100% * the weight of the lime/the weight of the ardealite. The cement mixing amount is equal to 100% * cement weight/phosphogypsum weight. The phosphogypsum is modified, the modified phosphogypsum semi-rigid base layer formed after modification has good freezing resistance, and the reduction of the UCS value after freezing and thawing cycle is small.
本发明公开了一种季节性冻土地区公路用改性磷石膏半刚性基层材料及其制备方法，由磷石膏、石灰水泥和适量水制成，其中，以磷石膏为基准，石灰掺量为1‑10％，水泥掺量为1‑10％，石灰掺量＝100％*石灰重量/磷石膏重量，水泥掺量＝100％*水泥重量/磷石膏重量。本发明通过对磷石膏改性，改性后形成的改性磷石膏半刚性基层具有良好的抗冻性，冻融循环后UCS值折减较小。
