Iron and steel slag used in road construction is manufactured by crushing and mechanical stabilization of blast furnace slag and steelmaking slag for use as paving material. The most common use is as an aggregate in the manufacture of asphalt. The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense (SSA is 20-30% heavier than naturally occurring aggregates such as basalt and granite). Use of Steel slag in Bituminous Road Construction • The iron and steel slag that is generated as a by product of iron and steel manufacturing processes can be broadly categorised as blast furnace slag and steel making slag. Slag is typically received in pots from steel furnace refining vessels contaminated with metal that separates to the bottom.

The electric arc furnace steel slags described in this paper are among the more interesting materials for application in the building sector. The research covers the construction and fiveyear performance of a pavement constructed with 30% steel slag. To achieve sustainable development, use of steel slag as a substitute to natural-aggregates has gained significant attention. Laboratory evaluation of mixes from steel slag aggregates was done by reconstituting mixes based on Ministry of Communications, Saudi Arabia, and Strategic Highway Research Program specifications. Specifically, Siam Steel Mill Services Ltd. provides the management of EAF slag in terms of handling, metal recovery and crucially the production of a quality slag aggregate for use in road construction. MATERIALS USED The performance was studied of three types of bituminous mixtures for road construction: 1. use of alternative materials in road construction. in road construction industries is gradually gaining significant importance in India, in light of the disposal, environmental problems and gradual depletion of natural resources, such as soil and aggregates. The research focused on the use of different types of slag in road construction in Ukraine. Use of blast-furnace slag's as • Sand and gravel for the construction of road beds, • Basic filler in asphalt–concrete mixtures for the construction of road and airport coatings, • Unroasted cement (binder) for reinforcing roadways and • Preparing slow-setting concrete. Abstract and Figures Steel slag is a byproduct from steelmaking industry and has been recycled in many countries around the world for decades. A Pennsylvania Department of Transportation study found that bituminous mixtures containing steel slag exhibited high stability, high skid resistance, and longer heat retention resulting in … We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. igy–YÍ.V?Îÿ“,V*@ĸ•ø…z ý낋/YËL֙«ufʘ6¥š¢.³ZÅ´’TS$JHÀ¶¢ÃI™¢•¢ÃIl­Òj5¬y‰V4ÀfÄÑl £¡]Wd¾åŒÌ´tÝëzš¶È*Ó¥z”(ˆj(&6DU‡¡)ÚÒôF:I[©ó3´ú›àä¿ÄÇ#|Ê°7»æ˜ò; $e9$„ ‚PàŠˆž´ûZ’(mT&Õ41*ø.

Structural behavious-of-high-strength-concrete, No public clipboards found for this slide, Use of steel slag in bituminous road construction. Asphalt concrete can be produced and the pavement constructed readily when crushed steel slag is used as a portion of the aggregate. Despite this, a large amount of steel slag generated from steel industries is disposed of in stockpiles to date. An ambitious road construction plan is underway in India, which primarily involves bituminous pavements. Looks like you’ve clipped this slide to already. Usage in road and hydraulic construction – Steelmaking slag can be processed to aggregates of high quality comparable with those of natural aggregates because of its high strength and durability. Experimental Study of Steel Slag Used a s Aggregate in Asphalt Mixture, 9(6), 753758. Utilization of waste materials in construction activities can reduce burden on these natural sources. Current research on steel slag in highway construction is focused on its use as an aggregate in HMA. • Blast furnace slag is recovered by melting, • separation from blast furnace that produce molten pig iron. This includes considerations regarding, not only the mechanical and chemical properties of the materials, but also their processing, storage, transportation, handling and potential for re-use.

On the other hand, large amounts of steel slag aggregates with good qualities are being produced and put to waste in Jubail, Saudi Arabia. It is also successfully used as an aggregate for concrete. Steel slag is residue from the steelmaking process, made of minerals like silica, alumina and titanium from iron sand, and combinations of calcium and magnesium oxides. In this study, a typical steel slag was collected from an M/s Jindal Steel Iindustry Pvt.Ltd Sinnar MIDC, (M.S) in India and its feasibility for use in different layers of road construction was investigated.
