Ferrous foundry slag is also used as coarse aggregate in HMA. How does Hot Mix Asphalt perform using Foundry Sand? In general, tests on mixtures of HMA containing foundry sand have performed as well or better than mixtures made with natural sands. Some foundry sands have shown improved moisture resistance and as well as increased rutting resistance. Pennsylvania DOT allows the use of

The slag processor may also be required to satisfy moisture content criteria (e.g., limit the amount of moisture in the steel slag aggregate prior to shipment to a hot mix asphalt plant) and to adopt material handling (processing and stockpiling) practices similar to those used in the conventional aggregates industry to avoid potential segregation. In addition, as previously noted, expansion

Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include. Blending with many other products such as granulated slag, fly ash and lime to form pavement material, skid resistant asphalt aggregate and unconfined construction fill.

Asphalt mixes containing foundry sand can be designed using standard asphalt mix design methods. As expressed previously, the amount of foundry sand used in an asphalt mixture depends largely on the amount of fines in the foundry sand. Studies have shown that foundry sand can be used to replace between 8 and 25 percent of the fine aggregate content in asphalt mixes.

Describes the results of a study by the Department of Civil and Environmental Engineering at the University of Wisconsin-Madison to assess metals leaching from industrial byproducts (foundry sand and foundry slag from a gray-iron foundry; and bottom ash and fly ash from a coal-fired power plant) used in highway construction. This study was funded by the Recycled Materials Research Center

Ladle Furnace Slag (LFS) may be used in substitution of fine aggregate (2–0.063 mm), and filler (<0.063 mm) in bituminous mixtures, considering its suitable particle size and hydraulic properties. From among the range of bituminous mixtures, this research is conducted on Porous Asphalt mixes (PA). Their high void ratio means they can absorb
