Phosphogypsum road base material and preparation method thereof
The invention relates to the field of road base materials, and particularly discloses an ardealite road base material and a preparation method thereof.The ardealite road base material is prepared from, by weight, 100 parts of an ardealite mixture, 0.2-0.4 part of a binder and 0.2-0.4 part of a curing agent; wherein the ardealite mixture is prepared by mixing ardealite lightweight aggregate and ardealite powder according to the weight ratio of (35-80): (65-20), and the ardealite lightweight aggregate is prepared by mixing large-particle-size ardealite particles with the particle size of 19-31.5 mm, medium-particle-size ardealite particles with the particle size of 9.5-19 mm and small-particle-size ardealite particles with the particle size of 4.75-9.5 mm according to the weight ratio of (3-4): 2: (2-3). The ardealite road base material provided by the invention has good pressure resistance, crack resistance, freezing resistance and water resistance, and the content of ardealite in the road base material is higher than 90%, so that the ardealite is easy to recycle.
本申请涉及道路基层材料领域，具体公开了一种磷石膏道路基层材料及制备方法，所述磷石膏道路基层材料由包括以下重量份的原料制备得到：磷石膏混合料100份、粘结剂0.2‑0.4份、固化剂0.2‑0.4份；其中，所述磷石膏混合料由磷石膏轻骨料和磷石膏粉料按重量比（35‑80）：（65‑20）混合制备得到，所述磷石膏轻骨料由粒径为19‑31.5mm的大粒径磷石膏颗粒、粒径为9.5‑19mm的中粒径磷石膏颗粒、粒径为4.75‑9.5mm的小粒径磷石膏颗粒按重量比（3‑4）：2：（2‑3）混合得到。本申请提供的磷石膏道路基层材料具有良好的抗压、抗裂、抗冻、抗水性能，由于磷石膏在道路基层材料中的含量高于90%，使得磷石膏易于回收循环使用。
