Abstract:
Purpose. This study case shows the influence of the use of electric furnace slag as an aggregate with a high positive impact on the properties of poured asphalt (AC). Research results regarding the skid resistance, depth of surface texture, resistance to erosion, water absorption, pressure solidity, and pellets of clay have argued the fact that adding this slag to mixing eruptive aggregate indicates improvements of mechanical characteristics of poured asphalt and its surface layer.
Methodology. Preliminary preparation of the poured asphalt blend preliminary mixture, sampling and examination of the properties are developed in accordance with standard methods: EN 12697-27:2000, SK EN 12697-36:2003, EN 12697-2:2002+A1:2007, EN 12697-8:2003, EN 12697-34:2004+A1:2007, (Marshall Test), EN 12697-6:2004, and SIST EN 12697-2:2004.
Findings.The metallurgical industries for years have been using all their by-products, including slag, as valuable resources for the industry and especially in the construction materials industry. The use of this process by-product in the construction industry, mostly in road construction, is among the key factors in saving natural resources and preventing environmental pollution.
Originality. For the preparation of the preliminary recipe for three types of poured asphalt (AC 0/11, 0/8 and 0/5 mm), electric furnace slag and the eruptive sand with grain size from 0 to 11 mm, 0 to 8 mm and 0 to 4 mm were used.
Practical value. The use of this type of slag as an aggregate of this bituminous mixture will not only show improvement of the physical-mechanical properties of AC, but will also show high economic and environmental effects.
