Use Geo-synthetic Fiber Strengthening Sub Project Details
| Abstract |
This project studies how geo‑synthetic fibers change the strength and stability of weak subgrade soils used in highway construction. Weak subgrade soils often have low bearing capacity and swell or shrink when they get wet, which can cause early pavement cracks and higher maintenance costs. To tackle these problems, the research adds lightweight polymer fibers to the subgrade layer, placing them just below the granular sub‑base. Lab tests—Standard Proctor compaction, California Bearing Ratio (CBR), and direct shear—measure how different fiber amounts and placement patterns affect the soil’s shear strength and load‑bearing capacity. The experiments aim to find the best fiber‑soil mix that gives the highest dry density and better resistance
to penetration. By linking fiber‑reinforcement details to subgrade stability, the study offers a clear method for cutting pavement thickness and lowering long‑term maintenance needs. The results give practical design advice for using synthetic polymers as sustainable, high‑performance reinforcement in modern road infrastructure.
