Abstract
Steel slag is a byproduct from either the conversion of iron to steel in a basic oxygen furnace, or the melting of scrap to make steel in an electric arc furnace. If not used it will end up in landfills costing money and causing environmental problems. Concurrently the world faces many problems with management of disposals. Nowadays many countries utilize their production of steel slag in different fields of industry such as cement industry and road construction. Many research papers have shown that using steel slag in road construction especially in asphalt mixtures has a lot of benefits. Therefore this study aims to evaluate the performance of hot mix asphalt (HMA) containing steel slag aggregate (SSA) as a coarse aggregate replacing the coarse portion of traditional aggregate in the Egyptian environment.
The physical characteristics of SSA were evaluated to determine its viability to be used in HMA. Six percentage of SSA (0%, 20%, 40%, 60%, 80%, 100%) were used to conduct HMA mixtures according to Marshall mix procedure. Two types of mixtures (4-C, 3-D according to the Egyptian code of practice classification) were investigated in this study. Mixtures performance was assessed using Marshall stability, flow, stiffness, indirect tensile strength (ITS), loss of stability test, dynamic modulus, and flow number test.
Results have shown that adding SSA to the HMA improving the mixtures performance. It was also observed that the 60% SSA is the optimal replacement percentage as the 60%SSA mixture improved all the mechanical properties. Based on these test results SSA could be especially beneficial in Egypt in both binder and surface courses.
