The effect of adding polypropylene fibers on the freeze-thaw cycle durability of lignosulfonate stabilised clayey sand

The possibility of confronting unsuitable soils in the construction site prompted the engineers to find a way to change inappropriate features of the natural soils. The process of changing the natural soil properties is referred to as soil improvement. Since the used soil from the site is exposed to sequential freeze and thawing conditions, it affects the mechanical and physical properties of the natural soil, leading to a reduction in strength...
