• Epoxy resin LR202 at 5 wt% significantly improves the freeze-thaw durability of silty sand, with samples resisting 12 cycles.
• The addition of glass fibers (0.4 wt% and 0.8 wt%) further enhances the durability and mechanical behavior of epoxy resin-stabilized soil.
• Ultrasonic pulse velocity (UPV) testing serves as an effective non-destructive method for evaluating the durability of epoxy resin-stabilized soils.
• Epoxy resin stabilization is a viable and environmentally favorable alternative for regions prone to frost and freeze-thaw conditions.
