STEEL SLAG UTILIZATION IN ASPHALT MIXES MF 186-1 Page 4 steel slag from furnace linings, but the major problem results from using ladles and pits as waste receptacles in the furnace areas. Fortunately, the value of steel slags is increasingly being recognized, particularly for return to blast furnace burden, and contamination is avoided.
Processing and beneficial use of steel slag, iron slag, and refractory bricks that were co-disposed with slag, reclaimed asphalt pavement materials (RAP) in quantities greater than 10 cubic yards and uncontaminated brick, block and concrete from sidewalk and highway projects as a construction material.
foundry sands, reclaimed concrete, and blast furnace slag. • Portland cement can contain fly ash, FGD gypsum, foundry sands, drywall, blast furnace slag, and steel slag. 3 Asphalt Surface Blast furnace slag, steel slag, and boiler slag can replace aggregate in the asphalt surface layer. 4 Asphalt .
Feb 17, 2004· furnace slag is a material not specifically covered by the definition of an industrial byproduct under s. NR 538.03(2), Wis. Adm. Code. The Department may determine other non-hazardous solid waste with similar characteristics as papermill sludge, coal ash or foundry slag .
Section 301 Base, Subbase, and Subgrade Aggregate 301.1 Description (1) This section describes requirements common to sections 305 through 313 and 350. Exceptions and additional requirements are specified in those sections. 301.2 Materials 301.2.1 General (1) Provide coarse aggregates from a department-approved source as specified under 106.3.4.2
ACAA, along with its partners, will promote and assist in developing new applications for the entire range of coal-ash products (fly ash, bottom ash, boiler slag, etc.), foundry sands, slag and other byproducts for use in construction of transportation systems.
Nonferrous Slags - Material Description ORIGIN Nonferrous slags are produced during the recovery and processing of nonferrous metal from natural ores. The slags are molten by-products of high temperature processes that are primarily used to separate the metal and nonmetal constituents contained in .
foundry slag was produced in 2008, of which about 90% was reused in a variety of engineering applica-tions such as aggregate in Portland cement concrete, asphalt concrete, aggregate base, fill material, and railroad ballast [17]. Of the total reused foundry slag, 40% was used as road basement and 10% was used as fill material.
Crushed concrete or other non-hazardous recycled materials, processed recycled asphalt pavements, bottom ash, foundry slag, glass and recycled crumb rubber Fly ash and bottom ash Coarse aggregate
Also in 1996, RRC began processing slag for asphalt and concrete uses. In 2005 RRC achieved inert status for it's processed foundry sand. RRCs recycled foundry byproducts have many end uses including as aggregate, ballast, scrap metals and water treatment media just to name a few.
The foundry's sand was used in place of soil to create road embankments, and crushed slag was used as roadway sub-base. The Falk Corporation and Briggs & Stratton foundries in Milwaukee participated in asphalt pilot projects undertaken by a major highway-paving firm.
Jan 20, 2019· The aim of this study was the evaluation and validation of the recyclability potential of asphalt mixtures that incorporate high proportions of by-products (electric arc furnace slag and foundry sand) and reclaimed asphalt pavement in their composition.

Recycled Asphalt Driveway Pros. Many homeowners have fallen in love with their recycled asphalt driveways. Here are some of the many benefits that the material has to offer: Affordable – One major advantage of using RAP for driveway construction is that it's very low cost. Recycled asphalt requires far fewer raw resources than asphalt.
about 17 to 24 million Mg foundry slag was produced in 2008 of which about 90% were reused in a variety of engineering applications as aggregate in portland cement concrete, asphalt concrete, aggregate base, fill material and railroad ballast. Of the total reused foundry slag 40% was used as road basement and 10% was used as fill material.
Beneficial use of waste foundry sand from ferrous and nonferrous casting foundries, system dust generated by ferrous metal casting foundries; or slag and refractories generated by ferrous metal casting foundries for use as roadway construction material, a component or ingredient in the manufacturing of concrete or asphalt products, a soil ...

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.
Waste foundry slag shall not be used as a component or ingredient in any concrete or asphalt product if the leachabie levels in Condition 2 are exceeded in the waste foundry slag, unless the leachabie levels are not exceeded in the asphalt or concrete product.,
Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
