Abstract:
In this paper,the application of phosphor-gypsum(a by-product of phosphorus chemical industry)as a road material is introduced,inclu- ding as a roadbed material and in asphalt application.The research status of phosphor-gypsum is described as an auxiliary material doped in lime- ash soil,cement and macadambase materials as well as a directly used roadbed material.By comparing with traditional roadbed materials,the high performance,environment-friendliness and desirable economy of phosphor-gypsum as a roadbed material are illustrated.Moreover,the ap- plication prospect and development potential of phosphor-gypsum in asphalt is also discussed,broadening the path for its comprehensive utiliza- tion.Combined with the current research status of phosphor-gypsum as a road material,the future direction of its development is considered and
envisioned.
