Evaluation of Physical, Chemical, and Environmental Properties of Biomass Bottom Ash for Use as a Filler in Bituminous Mixtures

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