Solving Lime Stabilization Issues Using Woven Geotextile in Soaked Conditions

This study investigates the engineering and geotechnical properties of poor subgrade soils and explores the use of lime and geotextile to improve soil properties. The aim is to enhance soil strength and mechanical properties in extreme conditions and address challenges associated with lime stabilization. Poor subgrade soil with low plasticity and strength can pose challenges to road construction and maintenance, particularly during the rainy season. In this study, experiments were conducted to evaluate the use of woven geotextiles on soaked lime-stabilized lateritic soils. Geotechnical tests, including particle size analysis, Atterberg, compaction, and California bearing ratio (CBR) tests were conducted. Geotextile was placed at varying depths under soaked conditions to evaluate the soil's bearing capacity. The findings indicate that the strength of lateritic soil was considerably improved by introducing geotextiles at different layers in the soil. It was observed that geotextiles placed at 3/5 the distance from the base showed a higher CBR value compared to the control results. The use of geotextiles has several advantages, including low maintenance, corrosion resistance, and increased service life of road pavement. In conclusion, geotextiles should be considered as a modernized approach to enhancing road construction on poor lateritic soils, particularly in wet situations where there are issues with lime stabilization.
