Influence of a Geotextile Made from Pineapple Leaf Fiber on Sandy-Clay Soils

Abstract

In response to the need for new high-performance materials in the road construction sector, this work focused on a geotextile made from Pineapple Leaf Fibres (FIFA) as reinforcement in four soil matrices of type A1 and A2 bar soil. An evaluation of the performance of soil-geotextile composite materials led to the conclusion. For all four soils, the loss of CBR value after immersion decreased very little with the incorporation of geotextiles. This incorporation of geotextiles in FiFA significantly improved the soil bearing capacity even after 96 hours of immersion. For all types of soil, the ability of geotextiles to improve the mechanical characteristics of soils, even in contact with water, has been demonstrated. In summary, geotextiles made from pineapple leaf fibers represent an ecological and sustainable alternative to traditional synthetic geotextiles because they have demonstrated good mechanical performance when incorporated into soils in dry and humid conditions, with the corollary benefits in terms of material reduction, costs, and environmental impact.
