A research experience on the construction of a pilot road section with a porous asphalt mixture
incorporating Ladle Furnace Slag (LFS) as fine aggregate in its composition is reported. The
pilot section consisted of overlaying this mixture on existing bituminous pavement and was
intended to simulate a real application of this sustainable construction material. Along with
the paving, quality control was conducted to ensure that this mixture complied with the
requirements of the current regulations for its use. This quality control included a durabilityperformance study. Thus, water-sensitivity, accelerated-aging and frost-exposure tests from
an abrasion-resistance approach were conducted on Marshall specimens compacted with 50
blows per face. The values obtained were compared with the abrasion resistance of unaged
specimens. The results of the tests were generally in accordance with the applicable
regulations, the full-scale porous asphalt mix with LFS exhibiting an adequate durability
performance in terms of abrasion resistance.
