ABSTRACT
Coir geotextiles, made from coir fibers, are natural geotextiles known for their high tensile strength and durability compared to other natural fibers. These properties can be further enhanced through surface modification techniques, making them even more suitable for reinforcement applications. In this study, pullout experiments were conducted on modified coir geotextiles embedded in lateritic soil samples within a large pullout apparatus. Additionally, a numerical simulation of the pullout tests was carried out to better understand the pullout mechanism. The results indicated excellent pullout interaction between the modified coir geotextiles and the lateritic soil, demonstrating the material’s enhanced performance. Modified coir geotextiles demonstrated 36% enhancement in pullout strength compared to unmodified coir geotextiles. With increased durability and tensile strength, these geotextiles emerge as potential substitutes for synthetic alternatives.
