Mining Wastes as Road Construction Material: A Review

The mining industry manages large volumes of tailings, sludge, and residues that represent a huge environmental issue. This fact has prompted research into valorization these wastes as alternative aggregates for concrete production, embankments, pavement material, etc. use resource construction presents two benefits: conserving natural resources reducing the impacts mining. In case road construction, not yet been developed on scale there is major lack specific legislation. gap due to variety exploited rocks, diversity mine residues, or valuable by-products slated valorization, specifics. paper review recycling including waste rock tailings. Those materials were mostly used in infrastructure where soils had initially poor geotechnical properties (low bearing capacity, frost susceptibility, swelling risk, etc.). Different directly stabilized by hydraulic binder through geopolymerization or, some cases, with bituminous treatment. Overall, will have considerable impact volume offering sustainable raw materials.
