As for mix design, Bowman shared that steel and blast furnace slag is often used as 100 percent of total aggregate in the mixture. The mixture depends on the application and cost. High performance mixtures cost more than a lesser performing mixtures.
How Is Slag Used In The Construction Industry. Steel slag is a by-product of the steel industry and can be used potentially as aggregate in asphalt mixture. This study evaluates the use of Steel Slag Aggregates (SSA) as substitute for natural aggregates in the production of hot mix asphalt (HMA) for road construction.
A Guide to the Use of Steel Furnace Slag in Asphalt and Thin Bituminous Surfacings 3 2.4 Processing - Crushing and Screening Steel furnace slag is processed in a manner similar to the production of aggregates at any quarry. Slag is fed to crushers and after reducing to the required maximum size is screened into the required grades. For asphalt and thin
