In this study, steel slag was used as an aggregate replacement in conventional dense graded asphalt mixes (ACW14 and ACB28). Steel slag was selected due to its characteristics, which are almost similar to conventional aggregates, and the fact that it is easily obtainable as a by-product of the steel industry.
Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance and water absorption capacity , .
Reclaimed asphalt pavement (RAP) consists of reprocessed hot-mix asphalt (HMA) pavement material, such as asphalt and aggregates. RAP often contains high-quality, well-graded aggregates that are coated with asphalt cement but may include steel slag, a by-product of steel making. Steel slag …
We utilize slag, a product of steelmaking, in versatile construction material for environmentally beneficial use. Applications include road construction, asphalt, ready-mix concrete, cement, railways ballast, mining, filtration and agriculture.
The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement.
