RESUMEN
Biopolymer-based soil treatments have shown effectiveness in soil improvement, with successful field-scale implementation. In this study, we explored the effect of cyclic wetting-drying (W-D) and freezing-thawing (F-T) on the strength durability of biopolymer-treated soils. The results indicate that cyclic W-D and F-T gradually degrade soil strength owing to water adsorption and local biopolymer dilution. Poorly graded sand was highly vulnerable to these weathering effects; however, this problem was mitigated when the soil contained a fines content of 15-25%. These biopolymer-treated soils effectively resisted numerous cycles of both W-D and F-T, indicating that biopolymer-treated soils are suitable for earthen slope reinforcement.
