In this research, the possibility of making a porous asphalt mixture manufactured completely with recycled aggregates from carbon steel production was explored. Electric arc furnace slag (EAFS) was used as coarse aggregate and ladle furnace slag (LFS) as fine aggregate and filler. Initially, the properties of both slags and their suitability to be used in the manufacture of porous mixtures were analyzed. Then, a series of asphalt mixtures were developed incorporating these slags and they were compared with a reference mixture, made with conventional components. A series of tests were performed, including concepts such as mechanical behavior, durability, moisture susceptibility, rutting resistance, permeability or skid resistance. The results show that it is possible to make a suitable porous asphalt mixture with 100% of steel slag aggregates, complying with the standard requirements and obtaining a durable and environmentally sustainable mixture.
