“…For Slurry Surfacing road pavements the optimum for usage still remain bitumen emulsions produced on distilled high-acidic bitumen obtained from heavy high-resinous low-paraffinic crude oil (Saghafi, 2019;Dong, 2018;Son, 2014;Apaza, 2021;Grilli, 2019;Terrones-Saeta, 2020;Johannes, 2014;Destree, 2022;Usman, 2019;Johannes, 2019;Izadi, 2020;Pyshyev, 2015). Still, such bitumens are highcost and not always available for usage due to deficiency on the market.…”

Pavement grade cationic bitumen emulsions formulations were developed for Slurry Surfacing based on orthophosphoric and hydrochloric acids with both all-purpose and specialized emulsifiers used. As a result, there were established relations of mix time upon cement - for Slurry Surfacing based on various acids and emulsifiers. Mix time of Slurry Surfacing mix (having different cement content) with bitumen emulsions on both orthophosphoric and hydrochloric acids is characterized by parabolic relation, branches of the parabola going down. Still, parabola slope steepness for Slurry Surfacing with cement and bitumen emulsions on orthophosphoric acid is higher than for emulsions on hydrochloric acid. The regularity investigated allows affirming that dosing cement for Slurry Surfacing with orthophosphoric-based bitumen emulsions shall be more diligently checked and controlled – so as to avoid the premature mix time.

“…The electric arc furnace slags have been used as an aggregate for hot mix asphalt [20,21], warm mix asphalt [22] and even for mixes with bituminous emulsion [23]; this shows its excellent mechanical characteristics and its use in developing high quality bituminous mixtures [24]. However, in most cases the characteristics of this by-product have not been maximized and its use has been relegated to low-level materials [25].…”

Road construction is an activity that demands a significant amount of aggregates for bituminous mixtures. In addition, these aggregates must be of a suitable quality for use, even more so on high traffic roads. In response to this problem, and in order to avoid the extraction of new raw materials, research is being carried out using industrial waste as a substitute for conventional aggregates. In this way, the extraction of raw materials is reduced and landfilling of waste is avoided. However, these wastes must have certain properties and environmental advantages over natural aggregates. Otherwise, the use of waste would not be environmentally beneficial but would be more damaging to the environment. For this reason, this research evaluates the viability of using electric arc furnace slag as aggregates for bituminous mixtures, the main objectives being the determination of the characteristics of the by-product, the particularities and the critical points to be taken into account for its subsequent use in mixtures. At the same time, the environmental advantages of treating this waste to obtain a usable aggregate are evaluated in comparison with the processing of a natural aggregate. The results showed that electric arc furnace slags have a suitable chemical composition and excellent physical and mechanical properties for use in bituminous mixtures, even on high traffic roads. At the same time, it was determined that their use produces a considerable reduction in environmental afflictions. Therefore, it could be affirmed that the use of electric arc furnace slags in bituminous mixtures is recommendable as a way to develop more sustainable materials for construction.

“…Research into the improvement of production processes is mainly based on the use of new techniques to reduce the temperature at which bituminous mixes are formed, as these are the main element in the production of high-quality, comfortable, and safe roads [18]. Temperature reduction techniques are mainly based on the use of bitumen emulsions [19], as the mixes are formed with this binder at ambient temperature, thus avoiding the heating of the bituminous mix at high temperatures by fossil fuels [20]. At the same time, and with the aim of reducing the extraction of raw materials, waste has been reused for the formation of bituminous mixtures.…”

Energy consumption, because of population development, is progressively increasing. For this reason, new sources of energy are being developed, such as that produced from the combustion of biomass. However, this type of renewable energy has one main disadvantage, the production of waste. Biomass bottom ash is a residue of this industry that currently has not much use. For this reason, this research evaluates its use as a filler in bituminous mixtures, since this sector also has a significant impact on the environment, as it requires large quantities of raw materials. With this objective, first, the physical and chemical properties of biomass bottom ashes were evaluated, verifying their characteristics for their use as filler. Subsequently, bituminous mixtures were conformed with biomass bottom ash as filler, and their physical and mechanical properties were analyzed through particle loss and Marshall tests. The results of these tests were compared with those obtained with the same type of mixture but with conventional and ophite aggregates. This study confirmed that biomass bottom ash was viable for use as a filler, creating mixtures with a higher percentage of bitumen, better mechanical behavior, and similar physical properties. In short, more sustainable material for roads was obtained with waste currently condemned to landfill.
