The increasing speed of temperature is slow when heating steel slag because of its pores. Heat could be released inside the steel slag ( Huang et al., 2013). The poor thermal efficiency of steel slag consumes additional fuel when preparing asphalt mixture. Extra asphalt binder and fuel depress the application of steel slag asphalt mixture.
