The construction of Embankment is a very common structure, used in civil engineering, where a range of materials are used to create a stable foundation for various structures. One such material that has been used is coal ash, which is a by-product of coal combustion; it is an attractive filler material as it is cheap, environment friendly, and available in abundant quantity from thermal power plants. Studies have shown that coal ash which has comparatively similar shear strength than natural soil can be used in embankment constructions. This review covers coal ash’s characteristics as a soil material, including its physical, chemical properties, and its suitability for use in geotechnical applications related to embankment construction. Subsequently, this study discusses several case studies and laboratory experiments that have been conducted to investigate the behavior of embankment using coal ash as a soil material. Additionally, the review highlights the different factors that affect the stability of these embankments, including geotechnical properties, the construction process, and the long-term performance of the embankment. At the end, future research aspects and design considerations by using of bottom ash in embankment construction has been discussed.
