In the construction industry, the interest for recycling aggregates is rising as more people demand for alternatives due to lack of supply of naturalaggregates and environmental problems. However, in order for recycled aggregates to be used in infrastructures, stability and other factors need to beverified. Therefore, the objective of this study is to analyze the sensitivity of soil properties to secure slope safety according to various heights ofembankment when bottom ash and dredged soil mixture is applied in the embankment. In most cases, all heights were safe for the slide for theembankment whether the water level is full or sudden draw down. The result of the sensitivity analysis revealed that the unit weight of embankments ishighest among all factors to be considered. However, the sensitivity of the unit weight became smaller and the sensitivity of the friction angle ofembankments increased with the height of embankments. The sensitivity of factors of core materials is very small because the core has weaker physicalproperties than those of the embankment. The effect of the height for each factor is different for each slope and water levels. The sensitivity of the unitweight of embankments is most affected when the height is 60m in the upstream slope. To conclude, bottom ash and dredged soil mixture can be appliedin the embankment and different factors must be considered in different scale because the sensitivity depends highly on the height of embankments.
