Pervious pavement, which has features of ventilation, temperature adjustment, and water permeation, has been viewed as one of the measures to mitigate the global warming problem. Consequently, using electric arc furnace to make pervious slag concrete is studied. The parameters used in the study include aggregate type, aggregate size, past void volume ratio and water-cement ratio, compressive strenght, connected void ratio, permeability coefficient, suspended solid test, and obstruct ratio were investigated. According to the experiment data, the basic features of electric arc furnace slag concrete and the feasibility of application of electric arc furnace slag concrete on pervious pavement are evaluated. The results indicated the electric arc furnace slag concrete has better mechanical properties and water permeability than other comparable nature aggregate. The compressive strength increases as the paste amount increases but decreases as the aggregate size increases. In addition, electric arc furnace slag concrete on the pervious pavement has better performance at suspending solid and obstruct ratio than other nature aggregate. The result of examining the water passing through the pervious pavement showed the quality of the water was not changed because of the cover by cement and the transient period of passing water.
