Effect of biomass fly ashes as road stabilisation binder
The purpose of the research was to study the usability of two biomass fly ashes as road stabilisation binders. Partial least square structural equation modelling was used as an analytical method. The analysis was based on chemical composition data on SiO2, Fe2O3, Al2O3 and CaO in binder component, compressive strength results (7d and 28d), water to binder ratio, biomass fly ash content in binder, density of the stabilised material and binder to soil ratio as reflective indicators. According to the study, the higher relative biomass fly ash content had a positive relationship with total binder characteristics but indicated reduced strength properties in the stabilised materials. Also SiO2, Fe2O3, Al2O3 and CaO in binder component and binder to soil ratio had a positive effect on strength properties. However, the effect of biomass fly ash content on water demand, and the relationship between water content and strength were not statistically significant in the model.
