Geocell is a honeycombing interconnected cellular confinement system made of, in general, different types of geosynthetics. It encapsulates infill material within its pockets (restricts from shearing off) and acts like a composite mattress to redistribute the incoming load to the underlying soil with lesser intensity. Thus, it improves the overall bearing capacity and stability of geo-structures. Its wide application includes foundations, railway and highway sub-structures, embankments etc. In highways, geocell-reinforced pavements have exhibited notable improvement in respect of carrying capacity, stability, and durability. For pavements, mostly the base and/or sub-base layers are reinforced with geocells overlying the weak subgrades. In this study, responses of geocell-reinforced flexible pavements are investigated using Plaxis-3D, an FE-based software for geotechnical issues. The study compared the effectiveness and performance optimization of pavement structures with single and multiple-layers of geocell systems. The outcome has depicted considerable betterment with respect to reduction in deformation, increase in bearing capacity, and improvement in material consumption. The objective envisaged would be a viable method to mitigate the scarcity of competent sub-structures for the construction of road network, fulfilling the demand of ever-increasing urbanization.
