The general permit is for the processing and beneficial use of post-consumer asphalt shingles tear-offs and pre-consumer asphalt shingles i.e. imperfections tabs trimming scraps etc.
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.
Jul 20 2021 A number of IRC materials have been used successfully as coarse aggregate in asphalt pavement including crushed concrete foundry sands hydrated coal fly ash and slag. Air cooled blast furnace slag and steel slag in particular provide good rutting resistance and superior friction properties making it a choice aggregate for the surface course.
Jun 03 2018 Thus some of the main industrial wastes that can be incorporated in asphalt mixtures as aggregate substitute are steel slag foundry sand and fly ash. This wastes are produced on a large scale on the planet and the literature shows that when treated for use in road pavements their mechanical properties are similar or superior to.
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.
Nov 09 2017 According to the Washington State Department of Transportations Use of Steel Slag Aggregate in Pavements report in 2015 a high iron oxide content in steel slag aggregates creates pavement that is both hard and dense making it a superior choice over natural aggregates such as rocks in creating hot mix asphalt..
Apr 08 2019 Spent foundry sand has been used as a substitute for fine aggregate in asphalt paving materials.61113 As spent foundry sand is a poorly graded fine sand largely sized between 0.3 mm and 0.15 mm 5 to 15 fines content passing 0.075 mm openings No. 200 sieve which essentially excludes it as a solid substitution for conventional fine.
May 27 2021 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.
May 31 2021 Slag asphalt achieves better durability shear strength dynamic torsional stiffness and tensile strength and stability bearing capacity compared with traditional asphalt.

Laboratory investigation on foamed bitumen bound mixtures made with steel slag foundry sand bottom ash and reclaimed asphalt pavement. The paper describes an experimental investigation on foamed bitumen bound mixtures for road pavements with the aggregate matrix entirely composed of industrial by-products such as steel slags foundry sand bottom ash and reclaimed asphalt pavement.
Sep 01 2003 3. what looks like different types of foundry slag. Surely there is a better description of this material than that. 4. There is no regulatory definition of slag. RE foundry slag JimMetalsCeramics Materials 7 Aug 03 2353. Aside from waiting on oxilumes analysis he is correct you can check with EPA. The question is if they find.
Dec 04 2014 Steel slag is a byproduct of iron and steel production by the metallurgical industries. Annually 21 million tons of steel slag SS is produced in the United States. Most of SS is landfilled which represents a significant economic loss and a waste of valuable land space.
Specifications Using Recycled Materials by Material. TxDOT has eliminated unnecessary requirements for virgin materials in its construction and maintenance specifications. Additionally we have approved specifications that specifically call for or allow for the use of recycled materials. Some specifications require their use while others allow.
Steel Slag - Asphalt Concrete INTRODUCTION Steel slag can be processed into a coarse or fine aggregate material for use in dense- and open-graded hot mix asphalt concrete pavements 123 and in cold mix or surface treatment applications. 4 Proper processing of steel slag and special quality-control procedures are extremely important in selecting steel slag for use in asphalt paving mixes.
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.
Jan 01 1997 The recycled materials shall include but are not limited to recycled asphalt pavement crushed concrete subbase foundry slag asphalt flux produced from the reprocessing or re-refining of used oil and paving materials utilizing recycled materials including but not limited to crumb rubber from automobile tires ash and glass and glassy aggregates.
