NOVELTY - Phosphogypsum stabilizing material, comprises natural aggregate, phosphogypsum lightweight aggregate and gel material. The natural aggregate includes natural aggregate with a particle size of 0-4.75 mm and natural aggregate with a particle size of 4.75-9.5 mm; the phosphogypsum lightweight aggregate includes phosphogypsum light aggregate with a particle size of 9.5-19 mm and phosphogypsum light aggregate with a particle size of 19-31.5 mm; the mass ratio of the natural aggregate, phosphogypsum lightweight aggregate and gel material is (40-50): (50-60): (7-11); the mass percentage of phosphogypsum in the phosphogypsum lightweight aggregate is 80-90%; and the gel material is phosphogypsum slag cement, and the mass percentage of phosphogypsum in the phosphogypsum slag cement is 40-50%. USE - The phosphogypsum stabilizing material is useful in road stabilizing layer (claimed). ADVANTAGE - The phosphorus gypsum stable material can realize large doping of phosphogypsum light aggregate, and can replace part of the gravel in the traditional stable material by using the phosphogypsum light aggregate (the mass ratio of the phosphorus graphene in the light aggregate is 80-90%) and gel material (common silicate cement).
