Abstract In this study, variable returns to scale (VRS) data envelopment analysis was integrated into the Taguchi approach to optimize ternary additives for expansive soil enhancement. The ternary additives selected were sawdust ash (SDA), quarry dus

Expansive soils are problematic due to the performances of their clay mineral constituent, which makes them exhibit the shrink-swell characteristics. The shrink-swell behaviours make expansive soils inappropriate for direct engineering application in

Soil dilatancy behavior is crucial in the numerical modeling of slopes for safety factor (SF) computation. The effect of dilatancy on the SF of stabilized expansive soils has been rarely reported. The present study thus focused on the effect of dilat
