Ladle furnace slag in asphalt mixes

Skaf, M. / Ortega-López, V. / Fuente-Alonso, J.A. / Santamaría, A. / Manso, J.M.

Highlights•LFS works properly as filler, presenting good adhesion with the bitumen.•The LFS had superior bitumen absorption than the conventional materials.•Porous mixes with LFS provided results in line with those of the standard mixture.•LFS mixes presented good cohesion and excellent mechanical behavior.

AbstractLadle Furnace Slag (LFS) may be used in substitution of fine aggregate (2–0.063mm), and filler (<0.063mm) in bituminous mixtures, considering its suitable particle size and hydraulic properties. From among the range of bituminous mixtures, this research is conducted on Porous Asphalt mixes (PA). Their high void ratio means they can absorb any eventual expansion of the LFS.Mechanical behavior, moisture susceptibility and durability are all tested. The results report the performance of the LFS mixtures, which showed compliance with the specifications of the relevant standards and no significant differences from those made of natural aggregates and cement.
