The results show how the utilization of BOF slag as coarse aggregate in road construction improves the technical performance of asphalt mixtures (Marshall Quotient 4.9 vs. 6.6). Moreover, the introduction of BOF slag into the asphalt mix as a coarse aggregate, instead of limestone, causes a carbon emissions reduction rate of more than 14%.

During steelmaking process, the viscosity of the slag varies with the temperature and slag compositions. To some extent, the variation of slag viscosity can be one or two order of magnitudes [ 23 ]. In this context, the gas-slag-metal interaction with varying slag viscosities was numerically investigated.
