“…However, when the mass was replaced, the adhesive properties of the asphalt-aggregate system worsened. On the basis of a study of a warm mix asphalt (WMA), [28] concluded that BFS can be used as a partial substitute for the coarse fraction of aggregates in WMA. When 21% of the coarse aggregates was replaced with BFS, the mixture's stiffness, resistance to moisture damage, and resistance to abrasion all increased beyond the levels achieved with the control asphalt mixture.…”

Iron production’s waste materials include significant quantities of blast furnace slag (BFS) which could potentially be used as a substitute for natural aggregates in hot mix asphalt (HMA) used in highway projects. Although many of properties of slag are interesting, its porosity and absorption rate would lead to greater consumption of asphalt. For this study, a Portland cement (PC) paste was used to reduce the porosity of a BFS. This PC treated BFS (called BFS-C) was then used in an HMA to replace the coarse fraction of a natural aggregate. Marshall, Indirect Tensile Strength (ITS), resilient modulus and Cantabro tests were then carried out on different HMA mixtures that included BFS-C. Using BFS-C, HMA’s resistance under monotonic loading, stiffness under cyclic loading, and resistance to moisture damage increased remarkably. In addition, the Cantabro abrasion resistance of BFS-C improved was better than that of the HMA mixture produced with untreated BFS.
