Application of various binders in soil stabilisation for road batter protection
The study investigates the use of various binders for soil stabilization to enhance road batter protection under extreme hydraulic conditions. Flash floods and high-velocity water flows in rural areas often lead to significant erosion, posing challenges for infrastructure sustainability. This research aimed to identify cost-effective and efficient binder combinations suitable for protecting soil surfaces against severe erosion. Disturbed soil samples were mixed with agricultural lime, gypsum, and triple blends at varying proportions and subjected to controlled weathering and flume tests at velocities of up to 2 m/s. The results revealed that triple blends, at proportions of 2 % and 3 %, demonstrated the most effective erosion resistance, with unconfined compressive strengths exceeding 1 MPa. In contrast, gypsum showed limited efficacy due to uneven binding distribution. The study concludes that optimal binder selection and application can significantly reduce erosion susceptibility, offering a sustainable solution for rural infrastructure protection.
