Increasing the Bearing Strength of Base Layer (WBM Roads) by Using Plastic Cells and Analysis Through Staad Pro

Abstract

Abstract Water-Bound Macadam (WBM) roads often grapple with limited traffic capacity and a shortened lifespan due to their inherent structural weaknesses, particularly when subjected to mixed traffic conditions. In response to these challenges, this research introduces a novel solution by incorporating plastic cells made from recycled PET bottles into the road’s foundational base course during construction. This innovative addition serves as a transformative enhancement, significantly bolstering the road’s strength and extending its longevity. To ensure the road’s structural integrity under load-bearing conditions, the study employs a dual approach, connecting two plastic cells through both plastic strips and rivet joints. Remarkably, our investigation underscores the superior robustness of the riveted connection method over its strip counterpart. Soil testing, conducted in accordance with IRC 28-1967 standards, provides a comprehensive comparison between specimens containing plastic cells and traditionally constructed roads, facilitating a straightforward assessment of their respective properties. This research adheres to established methodologies, tests, and requirements to fortify the durability of water-bound macadam (WBM) roads through the incorporation of plastic cells into the base course. Rigorous structural analyses conducted using Staad Pro ensure these innovations can withstand diverse loads, further substantiating their efficacy. Our overarching goal is to bolster the region’s infrastructure by enhancing road strength and load-bearing capacity through the integration of thoroughly tested materials, surpassing the performance of conventional roads. This study represents a significant stride towards achieving enduring and resilient road construction practices.
