An Unconventional Asphalt. Some Characteristics of Steel Slag Asphalt
Year: 2025
Type: article
Abstract: It has been known since ancient times that a good infrastructure is needed to develop an area. But because there are more and more areas in continuous development, raw materials are consumed with acceleration and the planet is becoming progressively occupied by waste, we are trying to find other materials than the classic ones to use in road construction. Ordinary asphalt mixtures have aggregates of different grades, filler and bitumen in their composition. If normally the aggregates used for the production of asphalt are extracted from nature, in this study we showed how we produced an asphalt with aggregates from crushed steel slag, an industrial waste, obtained after the manufacture of steel. Inside the article you will discover the establishment of recipes for asphalt mixtures with crushed steel slag, the making of samples and their testing according to the norms in force. The results obtained are encouraging, some characteristics of this asphalt being better than the asphalt prepared with classic aggregates. The use of crushed steel slag in areas where there are dumps with this waste could generate a double benefit: the release of some storage spaces and the production of a cheaper asphalt.
