Preparation and construction process of copper tailing slag road material

The invention discloses a copper tailing slag road material preparation and construction technology, and relates to the technical field of road engineering, the copper tailing slag road material comprises 92-97 wt% of copper tailing slag and 3-8 wt% of a low-carbon gel material; the total content of CaO, SiO2, Al2O3 and MgO compounds in the copper tailings is greater than or equal to 70%, the water content is less than or equal to 14%, the ignition loss is less than or equal to 20%, and the SO3 content is less than or equal to 3.0%; the low-carbon gel material is prepared from 80 to 85 weight percent of superfine slag powder and steel slag powder, 8 to 12 weight percent of gypsum powder, 6.5 to 10.5 weight percent of alkaline excitation material and 0.5 to 0.8 weight percent of additive. The preparation method of the copper tailing slag-based road material comprises the following steps: S1, preparing a low-carbon gel material; s2, preparing copper tailings; s3, preparing the road material.
