Germany alone has 650,000 km of road network. The main construction material used to build roads is asphalt. Our products are perfect for the production of asphalt and are already in use in a wide variety of locations. The reasons for this are clear. StahLith not only helps reduce the use of natural mineral aggregates, but it is even more suitable than the natural material itself. Particularly when slag is used in road surfaces, the surface is significantly more resistant to polishing and less susceptible to abrasion. Another major advantage is that the surface does not heat up as quickly, which significantly reduces the risk of dangerous blow-ups in summer.
