- GEOTECHNICAL PROPERTIES AND APPLICATIONS OF IRON ORE TAILINGS-AMENDED LATERITIC SOIL FOR ROAD CONSTRUCTION (2026) · Rudarsko-geološko-naftni zbornik · cited 2× · doi
The geotechnical properties of lateritic soils are often substandard, which can lead to road failures. There is a need for a sustainable and effective amendment to improve the geotechnical properties of lateritic soils. The use of IOTs as an amendment has been proposed, but there is a lack of research on its effectiveness.

The paper identifies the need to improve geotechnical structural and technological solutions using soil-cement. The study recognizes the gap in the current trends and technical designs for soil-cement applications. The research aims to address the limitations of existing solutions and develop new technical solutions with enhanced efficiency and expanded functional capabilities.
