Enhancing Pavement Performance through the Strategic Use of Geosynthetics in Infrastructure Design

Abstract

The demand for sustainable and resilient highway infrastructure has driven innovations in materials and design strategies, with geosynthetics emerging as key contributors to pavement performance. This paper investigates the application and benefits of geosynthetics—namely geotextiles, geogrids, geocomposites, and geocells—in highway pavement design. Their functions span separation, reinforcement, filtration, drainage, and erosion control, improving structural integrity, load distribution, and durability. Through a critical review of existing literature and case studies, the paper evaluates geosynthetics' role in mitigating reflective cracking, rutting, and subgrade instability. Comparative analyses reveal that pavements incorporating geosynthetics demonstrate enhanced mechanical performance and extended service life with reduced maintenance costs. The study concludes with recommendations for further research to address knowledge gaps and enhance geosynthetic integration for cost-effective, environmentally sustainable road construction.
