courses.3,4 The purpose of this paper is to review developments in steel slag asphalt mixes starting from a brief description of the range of slags available for use in pavement construction and maintenance5. Ferrous slags (iron blast furnace, steelmaking, foundry, ferro-alloy) are
Foundry slag is composed of fluxing agents and impurities removed from the molten metal prior to casting. Most foundry sands, as well as ferrous foundry slags, can be used as fine or coarse aggregates in construction and soil applications. In addition, this slag has also been used as coarse aggregate in asphalt and in road construction.
Sep 30, 2016· 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
Aug 09, 2015· Steel Slag for Asphalt Pavements . Engineering Properties of Steel Slag. An overview of the typical engineering properties of . steel slag can be seen in Table 7Table 5 and . Table 8Table 6.
George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016 10.4.3.6 Cold mix-foamed asphalt EAF steel slag, foundry sand,bottom ash, and reclaimed asphalt pavement (RAP) meeting physical and mechanical properties were mixed in variable proportions that satisfied the technical specifications for cold mixtures.

The foundry granulated slag is a waste generated in the process of cast iron production via cupola furnace. Previous studies have shown that this slag, with lower particle size, presents good
Nov 13, 2012· The past decade has seen the increased and successful use of reclaimed asphalt pavement (RAP), warm mix asphalt (WMA), reclaimed asphalt shingles (RAS), and ferrous; iron and steel slag (slag).
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.
commonly used materials in asphalt mixtures were blast furnace slag, steel slag, ground tire rubber, and cellulose fibers. Less commonly used recycled materials included fly ash and foundry sand. Total tonnage of WMA is estimated at 106.4 million tons in 2013. This
Foundry slag is composed of fluxing agents and impurities removed from the molten metal prior to casting. Most foundry sands, as well as ferrous foundry slags, can be used as fine or coarse aggregates in construction and soil applications. In addition, this slag has also been used as coarse aggregate in asphalt

May 05, 2015· Compressibility of recycled materials including bottom ash (BA), foundry slag (FSG), foundry sand (FSD), recycled asphalt pavement (RAP), recycled pavement material (RPM), recycled concrete aggregate (RCA), and recycled asphalt
foundry slag has been used as a substitute for native coarse aggregate in concrete m ixtures, it has also been used in asphalt mixtures. Here again, the slag is usually crushed to achieve the
Blast furnace slag is used in a variety of applications including structural concrete, mineral wool, and glass manufacture. Steel slag also has numerous applications, such as an efficient non-slip choice for asphalt pavement where friction is desirable. All slag
