| Abstract | ||||
| The use of steel slag aggregate in rigid pavement presents a great economical and environmental solution to overcome the decreasing in natural aggregate. The aim of this research is to investigate the potential recycling of Basic Oxygen Furnace Slag (steel slag) in road construction for sustainability an environmental benefit. The steel slag is used as a coarse aggregate replacement in rigid pavement mixes, partly or totally. Recycling ratios of 25%, 50%, 75% and100% are used. The results showed that using steel slag aggregate increases the mechanical properties of concrete, safe to use as aggregate at sulfate attacking when samples were submerged in 5% sulfate solution concentration. | ||||
