Utilization Of Geotextile for Soil Stabilization A-Review

The process of enhancing the subgrade soil’s load bearing capability and technical qualities to sustain pavements and structures is known as soil stabilization. This study investigated the use of geotextile as reinforcement to stabilize two soil samples (lateritic and clay). Particle size analysis, the Atterberg Limit test, the specific gravity test, the compaction test, and the California Bearing Ratio test were all conducted as part of geotechnical testing. The American Association of State and Highway Transportation Officials (AASHTO) classifies the two soil samples as A-7-6 and A-7-5, which are deemed to be “poor” subgrade materials. To assess the strength of the soil samples, CBR tests were carried out both with and without non-woven geotextiles, with the non-woven geotextiles being positioned in a single layer at a depth of H/4 from the top and base surfaces of the soil. The results revealed that adding non-woven geotextile to the soil increased its strength since it had higher CBR values (15.1% and 19.6%) when placed at depth H/4 from the base surface as opposed to depth H/4 (14.1% and 18.2%) from the top surface. The trial outcomes clearly show that the presence of geotextiles raises the soil’s CBR value; as a result, geotextiles should be used as a modernized method of enhancing road construction on subpar soils and to thin out pavement layers.
