| Abstract | The construction sector is one of the most demanding sectors for materials that exist today. Therefore, in order to avoid the extraction of new raw materials, it is necessary to use waste. This waste must present a series of physical and chemical characteristics that make it suitable for its employment. Therefore, in this investigation, ladle furnace slag is characterized for use as filler in bituminous mixtures. These slags are produced by the metallurgical industry in large quantities and represent a significant environmental problem. The slags were tested by analyzing their chemical composition and elementary physical properties. At the same time, and in order to evaluate the environmental viability, the environmental affections produced by the treatment of this material for its use as filler were calculated. These environmental results were compared with those obtained by processing of conventional filler. The detailed methodology reflected the chemical and physical feasibility of ladle furnace slags for use as filler, as well as the environmental advantage of processing this waste compared to commercial materials. In this way, the suitability of ladle furnace slags for bituminous mixtures and its feasibility for the creation of more sustainable pavements was assessed. |
