Abstract:

The study aims to fill literature gaps by suggesting methods of electrical conductivity to estimate the optimal ratios of bottom ash and bagasse ash to lime for the chemical stabilisation of expansive soils, followed by an extensive program of physical, mechanical and microstructural tests; finally, the applications are proposed from numerical analysis of road embankment on soft soil in Ballina, NSW, Australia. Therefore, the investigation can facilitate comprehending the complex behaviour of expansive soils treated with hydrated lime, bottom ash and bagasse ash, incorporating the electrical conductivity measurements and predicting their behaviour in the field through modelling analysis. As practical applications, the study proposes using bottom ash and bagasse ash with lime in lightweight constructions, which lowers the carbon footprint by reusing discarded agro-industrial wastes. This practice also facilitates tackling climate change impacts and assists the development of road infrastructure in regional areas with low costs.
