A construction method of an ardealite improved roadbed is characterized by comprising the five steps of ardealite mixture treatment, mixture curing treatment, solidifying material water-adding preparation in proportion, solidifying material improvement anti-cracking treatment and site spreading and testing. The requirements for road base strength and rebound modulus can be met, the construction method can be widely applied in the region lack of filled earth and the region having higher solid ardealite waste yield, the occupation on cultivated land of ardealite can be decreased, the environmental damage caused by the ardealite is reduced, and the waster is changed into wealth. In addition, the ardealite is subjected to solidifying and improving treatment, differential settlement of the roadbed can be reduced, the problem of differential settlement caused by the fact that a traditional roadbed adopts disordered fillers and is not well compacted is solved, and the service life of the roadbed is prolonged. 种磷石膏改良
