“…The mechanical properties (benefits and drawbacks) of WMA mixes can vary in a large range mainly depending on the amount of additive and the type of WMA technology used. Wide scientific literature exists addressing the assessment of mechanical properties and durability of warm-modified binders and mixtures [2][3][4][5][6][7][8][9][10][11].…”

The environmental sustainability of road materials and technologies plays a key role in pavement engineering. In this sense, the use of Warm Mix Asphalt (WMA), that is, a modified asphalt concrete that can be produced and applied at lower temperature, is considered an effective solution leading to environmental and operational benefits. The environmental sustainability of WMA can be further enhanced with the inclusion of steel slag in partial substitution of natural aggregates. Nevertheless, such innovative material applied at lower temperatures containing warm additives and steel slag should be able to guarantee at least the same performance of traditional hot mix asphalts, thus assuring acceptable mechanical properties and durability. Therefore, the purpose of this study is to investigate the rheological behaviour of bituminous mastics obtained combining a warm-modified binder and a filler (material passing to 0.063 mm) coming from electric arc furnace steel slag. To evaluate the influence of both warm additive and steel slag, a plain binder and limestone filler were also used for comparison purposes. Complex modulus and permanent deformation resistance of bitumens and mastics were assessed using a dynamic shear rheometer. Experimental results showed that steel slag warm mastics assure enhanced performance demonstrating promising applicability.

“…However, to reach acceptable and adequate mixture stability and rutting performance, road agencies may need to specify minimum production temperatures for WMA (Bennert et al 2011, Hanz and. Mo et al (2012) evaluated the effects of binder type on the rutting behaviour of WMA containing 2% Rediset using immersion wheel tracking test according to Chinese specification T0719-1993. The Data obtained showed that the use of SBS-modified binder improves mixture rutting performance.…”

“…Activation energy can be related to the asphalt binder thermal susceptibility. Mo et al (2012) show that addition of Rediset has a positive effect on the reduction of activation energy and thermal susceptibility of asphalt binders. For instance, it was observed that the activation energy of a base binder with 2% Rediset and without Rediset are 64,961 and 67,014 kJ/(mol K), respectively.…”

This literature review paper presents the effects of a chemical warm mix additive, named Rediset on the rheological properties of asphalt binders, laboratory performance of asphalt mixtures, field behaviour of constructed road sections, energy consumption and air pollution, physicochemical properties of asphalt binders and behaviour of asphalt mortar. The rheological effects of Rediset on asphalt binder were evaluated from the viewpoint of very high temperature properties (viscosity of asphalt binder and workability of asphalt mixtures), high temperature properties (rutting resistance of asphalt binders and mixtures), intermediate temperature (fatigue behaviour) and also low temperature cracking properties. Other topics such as the mechanisms of temperature reduction by Rediset, storage stability of Rediset modified binders, moisture susceptibility, mix design issues, volumetric properties and economic benefits were also investigated. The information reported in this paper will help decision makers to appropriately select, apply and evaluate this warm additive type. In addition, researchers can identify gaps in existing knowledge for future research.

“…n-Alkane (wax) modifier decreases binder viscosity thereby increases the effectiveness of covering a mineral mixture with a binder at lower temperature and improves compaction process [7,8]. n-Alkane additives are widely used as a binder modifier in Warm Mix Asphalt technology (WMA) [3,[9][10][11].…”
