Abstract: Underpinning of flexible pavements using geo- replicas — particularly geogrids has come a extensively espoused fashion to address the adding demands on road structure due to growing business loads and environmental challenges. This approach enhances the mechanical geste of pavement systems by perfecting cargo distribution, reducing stresses transferred to the subgrade, and minimizing face distortion similar as rutting and cracking. The objectification of geo-synthetic underpinning contributes to increased pavement life, bettered structural integrity, and reduced construction and conservation costs.
