| description | The invention discloses a steel slag and macadam mixed graded base material which comprises steel slag with the particle size not larger than 20 mm and macadam with the particle size ranging from 20 mm to 53 mm, the content of the steel slag is 50 +/-5 wt%, the balance is macadam, and the performance conditions of the steel slag are as follows: f-CaO (free calcium oxide) is smaller than 4 wt%, and f-MgO (free magnesium oxide) is smaller than 10 wt%. The mechanical property of the graded broken stone base material is improved, a new way for utilizing the steel slag is developed, the material has good plate body performance, high early strength and crack resistance and high deformation resistance, all performance indexes meet the requirements of related standards, the steel slag serving as industrial solid waste is adopted, and the cost is low. As fine aggregate in a graded base material, waste is turned into wealth, the environment is protected, and multiple purposes are achieved.
