Enhancement in asphalt concrete qualities by utilizing Ferronickel slag

The resulting reports from various programmes and associations that undertake technical criteria surveys in the field of applications of metallurgical slag, including ferronickel slag, conclude that these represent the valuable raw materials for the following industries: construction, production of cement (Portland, metallurgical cement), fire retardant materials, glass minerals, bituminous aggregates (concrete asphalt, cement blocks, paint & adhesive substances), etc. Ferronickel slag in Drenas based on its mineralogical contents, whilst primary it can be used for production of asphalt concrete, simultaneously will serve in additional improvement of some physical – mechanical qualities. Projection of quantities of bitumen, considering the ratio between aggregates and slag substances, is determined by the combination of analytical and graphical methods. However, production and review of physical and mechanical factors of asphalt cement has been determined in laboratory conditions, in accordance with EU standards methods EN (933, 1303 – 4, 13036-1, etc). Laboratory examination for consumable layers of asphalt cement AB 11s B50/70 with slag content has demonstrated advanced qualities associated with: stability, roughness, flexibility, water absorption, plasticity, effects of bitumen usage, durability of road construction, etc
