Abstract:The urban construction waste will increase the difficulties of urban environmental protection management in the development and construction of city, and at the same time, speed up the consumption of stone resources. In order to coordinate the contradiction between the city construction and the urban construction waste, the study result shows that the building gravel can be taken as the building recycled material and can be used in the urban road construction. Combined with Shanghai S7 Highway (Yueluo Highway - Baoqian Highway) New Construction Project, the construction technology, filling scheme and quality acceptance of building gravel in the "perpetual - temporary combined" construction road are introduced, which has fully demonstrated the feasibility of building gravel recycling in the roadbed project and provides a new idea with the great application value for the treatment of urban solid wastes.
