“…According to the hypotheses developed, and taking as a basis a new circular economy in which waste is the raw material for new materials [3], various research projects have been carried out in which industrial by-products were used in bituminous mixtures [4,5]. The wastes used in bituminous mixes have been ladle furnace slag [6,7], electric arc furnace slag [8], reclaimed asphalt pavement [9,10], scrap tyres [11], recycled glass [12], ceramic dust [13], etc.…”

The road construction sector is one of the most raw material-intensive sectors in existence. As a result, it has a significant impact on the environment. For this reason, there are several research projects in which industrial by-products are used as raw materials. In turn, energy production from biomass combustion is considered to be one of the most promising energy sources. However, this type of energy produces a number of wastes that need to be treated, such as biomass bottom ash. This research evaluates the properties of biomass bottom ash for use as a filler in bituminous mixtures and quantifies the environmental advantages of its use. For this purpose, the chemical composition of the ashes was analysed and their properties were physically characterised to confirm their suitability as a filler. Subsequently, the advantages of its processing compared to limestone filler, lime, or cement were calculated with SimaPro software. The results showed acceptable properties of biomass bottom ash for use as a filler, as well as a drastic reduction in the environmental impact of its processing. In short, this research presents the basis for the development of further bituminous mixtures with biomass bottom ash, reducing the extraction of raw materials and avoiding landfill disposal.

“…The positive experience of different applications of wood ash in the construction industry has inspired a growing number of wood ash application studies for usage in pavement structures. One of these studies was a laboratory evaluation of the influence of wood bioash (BA), as part of the filler in an asphalt mixture, on the physical-mechanical properties of the mixture, as described in [23]. Different laboratory tests were carried out on the asphalt mixture of asphalt concrete type AC 16 surf, which is used for the construction of leveling layers and wearing layers.…”

“…The indirect tensile strength values of water-conditioned (ITSw) samples are the highest in the case of an asphalt mixture with a 25% content of bio-ash (BA) in the filler, while, in the case of the dry (ITSd) samples, they are highest in the asphalt mixture with 50% bio-ash (BA) content in the filler, which has an impact on the increased resistance of the asphalt to the appearance of cracks. As the results of the laboratory evaluation of [23] showed, wood ash can replace part of the stone filler in asphalt mixtures with 50% content, improving the performance of the asphalt mixture. According to the described laboratory evaluation [23], research on asphalt mixtures using wood ash in the filler is continuing, and one of these studies is described in this article.…”

The intensive construction of all categories of roads and the very demanding maintenance of the pavement structures of existing roads due to ever-increasing traffic loads confronts us with a lack of resources and also an increase in cost for the constituent materials of asphalt mixtures. On the other hand, there is another problem: large amounts of waste material in the form of bio-ash, which is obtained by burning waste wood biomass in the production of thermal energy and/or electricity. In order to solve the environmental problem of bio-ash disposal, research was conducted on the use of waste bio-ash as a constituent material in asphalt pavements. As part of this study, the effect of asphalt concrete mix, with bio-ash as a filler, on the release of harmful substances into the environment was investigated. The possibility of using wood bio-ash (BA) as a filler in asphalt mixtures was then determined through physical and mechanical property tests. The properties of the asphalt sample’s sensitivity to the action of water (indirect tensile strength ratio—ITSR) and resistance to rutting were tested for asphalt concrete type AC 11 surf with 50% bio-ash in the filler. It was established that asphalt concrete does not release harmful substances into the environment and that the 50% share of bio-ash in the filler results in asphalt that has good resistance to water sensitivity and even greater resistance to rutting.

“…y "¿cuáles son los efectos de beneficio?" [20], y así aliviar la dependencia de petróleo con alternativas al ligante asfáltico [21], con gran potencial de rendimiento en las mezclas, dentro de ellos, los subproductos obtenidos de la combustión de biomasa como las cenizas volantes [22] y los bioaceites. Otro proceso de transformación de la biomasa es la pirolisis, obteniendo bioaceite, biocarbón y gases [23].…”

La ingeniería de pavimentos, busca con ahínco materiales no petrolíficos como sustituyentes/mejoradores del asfalto. La producción de bioasfalto con biomasa es la técnica más usual con beneficios económicos, sociales y medioambientales. Este documento tiene como objetivo realizar una revisión literaria del mejoramiento del asfalto con biomasa en subproductos de biocarbón o bioaceite. Se efectuó una revisión de 80 artículos científicos, los cuales estudiaron las propiedades convencionales y reológicas del asfalto con porcentajes óptimos de adición de biomodificadores, considerándolos como nuevas tecnologías en las construcciones viales. Los resultados muestran que la dosis y tipo del biomaterial influye mucho como modificador, dado que el rendimiento del bioasfalto a base de biomasa garantiza reacciones positivas con una mínina adición de 1% de aceite de palma hasta 100% de ceniza de madera como máximo. En conclusión, a mayor dosis de biomodificador a altas temperaturas mayor es la mejora en la viscosidad, estabilidad, grado de penetración, punto de reblandecimiento, resistencia a la tracción indirecta, módulo de resistencia, resistencia a la deformación, resistencia a la fatiga, resistencia al deslizamiento y resistencia a la humedad del asfalto, además de tener mejores condiciones de envejecimiento oxidativo, pues generalmente el ligante asfáltico es compatible con la mayoría de los biomateriales, siendo viable como fuente de energía renovable, sostenible y de calidad.
