Abstract
Asphalt and concrete road surfaces are an essential part of the infrastructure of transport systems, and in recent years slag road asphalt has gained popularity as an efficient and environmentally friendly alternative. Slag asphalt, produced by incorporating slag, a by-product of industrial steel production, into asphalt concrete mixes, is the subject of this review article. The article presents a review of researches papers on the use of slag road asphalt. This article reviews the composition, production and physical and mechanical characteristics of slag asphalt concrete. Particular attention is paid to studies of the effect of slag on the strength, fracture resistance and deformation of the material. The authors provide an overview of the various methods of modifying slag asphalt to improve its performance and durability of road surfaces. The article also highlights the environmental importance of slag asphalt, generalized its ability to reduce the use of natural resources and reduce waste from the steel industry. The overall analysis of these articles suggests the potential of using slag road asphalt concrete as an effective and environmentally sustainable material in road construction. However, further research and practical tests are needed to confirm its applicability in different climatic and road conditions. The final part of the article discusses the significance of slag asphalt concrete in the context of sustainable road construction. The potential of slag asphalt to save costs in the construction and maintenance of road infrastructure, as well as to improve its durability and sustainability, is emphasized. In conclusion, the article provides a generalised overview of slag asphalt concrete, its advantages and promising applications in road construction.
