The use of aggregates with high abrasion resistance is essential for the correct long-term operation of railway lines. However, the extraction of these aggregates is not always cost effective and the creation of new alter natives with a lower life-cycle cost and a reduced environmental impact is fundamental for the environmental and economic sustainability of railway infrastructure. The new recycled aggregate from electric arc furnace slag (SFS-Rail) is proving highly satisfactory as it has excellent physical and mechanical properties. [ABSTRACT FROM AUTHOR]
