<p>Road infrastructure has short pavement lifespans and subgrade instability, requiring costly maintenance. This study looks at using high-elevation pine needles as a sustainable geotextile to improve construction and management. Benefits of this approach include the use of a readily available natural resource, cost effectiveness, and a lower environmental impact than more conventional materials like asphalt. The geotextiles are made using the natural fibers intrinsic qualities and are made from hand-picked pine needles that are chosen according to temperature, soil type, and altitude. Durability is increased by the moisture and UV resistance provided by the natural pine resin. In the production process, the pine needles are braided into geotextiles that adhere to ASTM D6381 and IS 15869–2020 standards. The incorporation of these geotextiles into the road structure improves water retention, load distribution, and ground stability. Environmental compatibility tests, durability studies, and mechanical testing are all part of comprehensive characterization. A validated numerical model was created to forecast performance and analyze soil-geotextile interactions. Research indicates that these geotextiles have the ability to increase the lifespan of roads and bridges. As a sustainable substitute for asphalt in road pavements, there is potential for widespread adoption in the future. The following UN Sustainable Development Goals (SDGs) are directly impacted by this research: SDG 9, SDG 11, SDG 12, and SDG 13. In order to produce infrastructure that benefits society and the environment, our research promotes sustainable road construction and maintenance.</p> Graphical Abstract <p></p>
