Biobased hydrogel for microstructural reinforcement and sustainable rainfall erosion resistance in expansive soil slopes

Key Points

• Enhanced rainfall erosion resistance was achieved using biobased hydrogel, which stabilizes expansive soil slopes.
• The hydrogel led to a significant increase in microstructural reinforcement, improving soil cohesion and reducing erosion risk.
• Assessment using soil testing procedures showed that treated slopes exhibited superior performance compared to untreated controls.
• These findings suggest that biobased hydrogel can be a sustainable solution for soil erosion challenges, highlighting its potential environmental benefits.
