Reinforced fill structures with geogrid reinforced soils are preferred for their cost-effectiveness, durability, and adaptability over traditional systems. However, still some challenges exist, particularly the long-term creep behavior of geogrids. While geosynthetics exhibit creep at high stress levels, realworld confined conditions typically impose lower tensile stresses. This study addresses these gaps through an optimized design approach and explores recycled aggregates as sustainable fill alternatives.
