“…As shown in Table 2, both BOF and EAF have high ferrous and ferric oxides. The presence of iron oxide in steel slag makes it relatively heavier than natural aggregates [51,62,63]. Due to the chemical composition derived from oxidizing environment, steel slag obtains dark greyish colour [25,64].…”

Road construction involves large quantity of construction materials, primarily obtained from natural sources. Utilization of waste materials in construction activities can reduce burden on these natural sources. To achieve sustainable development, use of steel slag as a substitute to natural-aggregates has gained significant attention. Steel slag as aggregate has many well-known applications in road construction such as, hot mix asphalt, cement concrete mix, antiskid-layer, granular-base and subbase layers. This paper review development in various aspects of utilizing steel slag aggregate in dense graded hot mix asphalt. Properties of steel slag can significantly influence performance of roads. Chemical composition and physical and mechanical properties of steel slag have been reviewed in consideration of its suitability in asphalt mix. Findings from asphalt mix design studies indicate that, steel slag asphalt mix can be designed to satisfy both volumetric and mechanical properties. However, caution need to be exercised to ensure that addition of steel slag does not lead to undesirable change in performance of mix. Review of laboratory and field performance evaluation studies related to skid, m oisture, fatigue and rutting failures are presented in the paper.

“…En [59], basados en múltiples estudios consultados, se hacen reportes sobre nueve escorias BOF y once EAF, composición química similar a las reportadas en la tabla 2. Los resultados presentados en la tabla 2 son coherentes con los reportados por [30,73] sobre cuatro tipos de SS estudiadas en Suecia y por [8,50,53,74,75].…”

“…La composición química y la microtextura rugosa de las SS permite que se formen fuertes entrecruzamientos de partículas [78,79] y enlaces adherentes con el asfalto [49,50,[80][81][82]. En [59], basados en las propiedades hidrófobas de una BOF y un pH cercano a 12, señalan que este material proporciona buena adhesión con el asfalto y ayudan a resistir fenómenos como el stripping. En [54], basados en imágenes obtenidas con microscopía electrónica de barrido (SEM) de una escoria EAF, reportan que estos materiales pueden desarrollar una adhesión más fuerte con el asfalto en comparación con mezclas convencionales, principalmente por su porosidad.…”

En la fabricación de mezclas asfálticas se consumen grandes cantidades de agregados pétreos de origen natural lo que impacta negativamente el ambiente. Estos agregados pueden ser sustituidos parcial o totalmente por otros que son desechados en escombreras y producidos por las compañías siderúrgicas, como las escorias de alto horno (BFS) y acero (SS). Estos dos últimos materiales poseen propiedades químicas y físicas que los hacen aptos para ser utilizados en múltiples aplicaciones como la construcción, mantenimiento y rehabilitación de carreteras. En el artículo se presenta una revisión del estado del conocimiento del empleo de BFS y SS en la producción de mezclas asfálticas, se describen y definen ambos materiales, se presenta la problemática ambiental, su riesgo toxicológico de uso, sus propiedades químicas y físicas, las ventajas y limitaciones de uso y la forma como han sido estudiados para ser empleados como agregados pétreos de mezclas asfálticas. Con base en la revisión bibliográfica realizada, los autores al final del artículo exponen algunas recomendaciones para continuar los estudios tendientes a sustituir agregados pétreos naturales por BFS y SS en la fabricación de mezclas asfálticas.

“…The use of secondary and waste materials, slag and dross materials, to substitute certain parts of asphalt mixes is not a novelty in the past decades with a constant pursuit for a better sustainable environment, and asphalt industry [16,17,18]. Research has shown that the use, instead of disposal, of such byproducts may be a promising way, amongst others, having at least no negative effects on performance while solving part of some issues related to the accessibility of virgin materials [19,20].…”

Asphalt industry finds itself battling ongoing economic difficulties and an urge to achieve a more sustainable development and growth. it means constant searching is needed for alternative materials and possibilities to use recycled and processed waste materials in asphalt mixes as long as an expected level of performance and durability is provided. Aluminium dross is a recyclable by-product of the casting process of melted aluminium. in this study an attempt was made to reveal the potentials of using aluminium dross as filler for asphalt wearing course mixes. During the research, filler fractions (d<0.063 mm) were prepared by milling and microstructural tests were conducted both on the alternative and control filler for a better understanding of the materials and their composition. the effect of replacing limestone filler with aluminium dross filler on the performance of asphalt mixes was analysed by performance-based and performance related asphalt mechanical tests according to common standards. in the paper, the properties of fillers and various mechanical test results are presented and by interpreting the tests and results final conclusions are presented regarding the use of aluminium dross as filler in asphalt mixes. keywords: asphalt, aluminium dross, filler, rheology, stiffness kulcsszavak: aszfalt, alumínium salak, töltőanyag, reológia, merevség member of the member of the Hungarian scientific Association for transport bella UDvarDi, bSc Graduated in 2017 as material engineer, Bsc. currently working on her msc diploma work.
