Recycling of Industrial Waste as Soil Binding Additives-Effects on Soil Mechanical and Hydraulic Properties during Its Stabilisation before Road Construction.

To improve the in situ soil stabilization, different chemical additives are used (ion exchange compounds, additives based on HSO or vinyl polymers, and organic additives using lignosulfonates). One interesting alternative is the production of additives from various waste materials. The extensive testing of waste-based blends with soil was performed; the mechanical (unconfined compressive strength (UCS)) and hydraulic (capillary rise, water absorption, and frost resistance (FR)) soil properties were measured.
