Review on Optimizing CBR of Expansive Soil Subgrades Using Woven Geotextiles for Road Construction

Authors- Rammohan Sharma, Hariram Sahu

Abstract-strength, high moisture sensitivity, and volume instability. Expansive soils, such as silty clay, exhibit significant swelling and shrinkage behavior, often resulting in pavement failure. This review evaluates the effectiveness of woven geotextiles in improving the California Bearing Ratio (CBR) of expansive soils, focusing on their reinforcement capabilities, placement depth optimization, and comparative performance. The study discusses previous research findings, highlighting the advantages of geotextiles as cost-effective, durable, and sustainable solutions for subgrade stabilization. It concludes by emphasizing the potential of woven geotextiles in addressing the limitations of traditional stabilization methods and providing recommendations for future studies.
