The general conclusion of the work was that the particular residue material, IRM, when stabilized with cement and cementitious substances may be a viable aggregate for reuse in construction of road bases. Most of the physical and mechanical properties of steel slags are similar or better compared to conventional crushed stone aggregates. The degree of slag utilization needs to be improved as an important measure to these problems. However, because slag contains heavy metals at concentrations that are higher than in most soil, questions have been raised regarding the need to evaluate the potential human health and environmental hazards associated with current applications. Soaked California bearing ratio (CBR) values of 153% and 128% for WBFS and FBFS respectively meet the bearing strength requirement for their use in base and subbases. Two types of TRS profiles were selected for this study such as raised and inverted rumble strips and middle overlapped rumble strips. BOF slag-bitumen mixes have shown better resilient moduli, rutting resistance, bonding and moisture damage resistance and stripping resistance than mixes with natural aggregates and they can also be high quality substitutes for natural aggregate in lower road pavement layers. Steel black slag characterisation for road construction 2.1.1. Residents say slag quickly leads to gravel roads "wash-boarding," or bumps across the road that can send vehicles skidding. Steelmaking slag is an integral part of the steelmaking process. Such slag is a valuable raw material for preparation of macadam materials and mineral binders serving as a base for asphalt concrete mixtures and manufacturing of cement emulsions, which are widely used in road paving. value, water absorption, surface texture, stripping, and flakiness.
