Abstract

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.

松针土工布在可持续道路建设和养护中加固路基路面性能的综合综述

道路基础设施的路面寿命短，路基不稳定，需要昂贵的维护费用。本研究着眼于使用高海拔松针作为可持续土工布，以改善施工和管理。这种方法的优点包括利用现成的自然资源，成本效益高，并且比沥青等传统材料对环境的影响更小。土工布使用天然纤维的固有品质，并根据温度、土壤类型和海拔高度选择手工采摘的松针制成。天然松木树脂提供的防潮性和抗紫外线性增加了耐用性。在生产过程中，松针被编织成符合ASTM D6381和IS 15869-2020标准的土工布。将这些土工布结合到道路结构中可以改善保水性、荷载分布和地面稳定性。环境相容性测试，耐久性研究和机械测试都是综合表征的一部分。建立了一个经过验证的数值模型来预测土工织物的性能并分析土工织物的相互作用。研究表明，这些土工布有能力增加道路和桥梁的寿命。作为道路路面沥青的可持续替代品，在未来有广泛采用的潜力。以下联合国可持续发展目标（SDG）受到本研究的直接影响：SDG 9、SDG 11、SDG 12和SDG 13。为了生产有利于社会和环境的基础设施，我们的研究促进可持续道路建设和维护。图形抽象
