The paper presents the geotechnical characteristics and slope stability analysis of moorum blended with fly ash for the construction of road embankments. The paper presents the geotechnical characteristics and slope stability analysis of moorum blended with fly ash for the construction of road embankments. An experimental investigation has been carried out on the moorum and moorum–fly ash mixes at various proportions of fly ash (i.e., 0%, 15%, 20%, 25%, and 30%) by dry weight of moorum. The index properties of moorum mixes and strength characteristics were evaluated by conducting Atterberg’s limit, specific gravity, grain size analysis and compaction parameters, direct shear parameters, and California Bearing Ratio (CBR) test, respectively. The stability analysis of moorum embankment was performed using FLAC/Slope 7.0 (Fast Lagrangian Analysis of Continua/Slope version 7) software at a slope angle of 30° and various heights of 4.0, 5.0, and 6.0 m to determine Factor of Safety (FOS). The maximum FOS was obtained at 30% of fly ash mix in moorum with 6 m height of the embankment.
