“…The substitution ratio and the particle size of the slag seem to determine its performance, as well as the binder chosen and the aggregate used as reference. Similar performances were established for the moisture susceptibility of the slag mixes, as in Sofilić et al (2010b), Wang and Wang (2011) and Wen et al (2016). Various studies found that when using EAFS both as coarse and fine aggregate, the samples resulted in higher dry and wet ITS and better TSR (Pasetto and Baldo, 2010.…”

“…A range of studies have shown higher slag mix resistance to permanent deformations as a result of creep stiffness and rutting (Ahmedzade and Sengoz, 2009;Ali et al, 1992;Ameri et al, 2013;Amuchi et al, 2015;Behnood and Ameri, 2012;Li et al, 2015;Pasetto and Baldo, 2011Pasetto et al, 2017;Wen et al, 2016;Wu et al, 2007). Their results were explained by the coarse aggregate properties, particularly high angularity, hardness, shear strength, resistance to wear and polishing of the slag particles.…”

“…Finally, steel slag pavement abrasion resistance was higher, as stated by Li et al (2015), who found that the Cantabro wear loss met the requirements for permeable courses. Wen et al (2016) also proposed taking advantage of the steel slag hard aggregates, to mitigate studded tire wear. Bagampadde et al (1999) observed worse results for slag samples in fatigue testing and this effect was increased with the limestone substitution percentage.…”

“…Ziari et al (2015) showed that the fatigue life of steel slag mixtures was higher when the EAF slag was used either as the coarse or the fine fraction, but their results were unacceptable in the four-point beam fatigue tests on 100% slag mixtures. Wen et al (2016) showed that top-down fatigue cracking resistance was unaffected in slag mixes with the addition of up to 60% of the aggregate.…”

Electric Arc Furnace (EAF) slag, a waste stream in the production of carbon steel, has interesting and extensively researched mechanical properties as an aggregate in asphalt mixes. In this paper, an exhaustive review is conducted of its main features, the problematic aspects of its use, and the main properties of the mixes prepared with this aggregate, such as mechanical behaviour, resistance to fatigue and permanent deformation, water sensitivity and skid resistance. Based on the literature review and own experience, the conclusion is that the use of EAF slag is generally recommended in partial replacement of the coarse aggregate, in all types of asphalt mixtures, following suitable pre-treatment. This usage improves mechanical performance, durability and long-term sustainability of the bituminous mixtures. Moreover, resistance against slipping and skidding on EAF slag pavements is an important safety-related aspect that makes them especially suitable for rainy regions.

“…As an ideal secondary resource, steel slag has been widely applied in civil construction, including pavement, concrete masonry and building materials in recent years. Previous experiments proved that steel slag asphalt pavement is feasible due to its higher stiffness, better abrasion resistance, lower fatigue, and lower permanent deformation properties [18,19]. Hence, the utilization of steel slag in asphalt mixtures can be conducive to natural resource savings and release of environmental pressure.…”

Microwave Absorption Ability of Steel Slag and Road Performance of Asphalt Mixtures Incorporating Steel Slag

et al. 2020

Excessive usage of non-renewable natural resources and massive construction wastes put pressure on the environment. Steel slags, the main waste material from the metal industry, are normally added in asphalt concrete to replace traditional aggregate. In addition, as a typical microwave absorber, steel slag has the potential to transfer microwave energy into heat, thus increasing the limited self-healing ability of asphalt mixture. This paper aims to investigate the microwave absorption potentials of steel slag and the effect of its addition on road performance. The magnetic parameters obtained from a microwave vector network analyzer were used to estimate the potential use of steel slag as microwave absorber to heal cracks. Meanwhile, the initial self-healing temperature was further discussed according to the frequency sweeping results. The obvious porous structure of steel slag observed using scanning electron microscopy (SEM) had important impacts on the road performance of asphalt mixtures. Steel slag presented a worse effect on low-temperature crack resistance and water stability, while high-temperature stability can be remarkably enhanced when the substitution of steel slag was 60% by volume with the particle size of 4.75–9.5 mm. Overall, the sustainability of asphalt mixtures incorporating steel slag can be promoted due to its excellent mechanical and microwave absorption properties.
