Bioash - A New Alternative Road Construction Material

In recent years, bioash is increasingly being researched as a potential building material. Bioash can be defined as a byproduct of energy production from biomass combustion. Through history, smaller, locally occurring, ash amounts were mostly treated as waste or were often used in agriculture. Today, it is necessary to find better ways of recycling larger amounts of bioashes generated in powerplants, which are created as a result of the European Union Renewable Energy Directive. Bioash usage as an alternative construction material could have great ecological and economic benefits, but there are also some obstacles and difficulties with its wide application. Research has shown that bioash has the potential to be used as an alternative material in various construction projects. It could potentially be used in structural and nonstructural concretes, bricks, in earthworks, and others, either as a binder or a fine aggregate. Road construction requires large amount of materials and as such could serve as a way of bioash recycling. Especially in low-volume roads to which lesser demands from traffic loads are set. This paper deals with the application of bioash in road construction.
