For construction of approaches to flyovers and Road Over Bridge’s, Reinforced earth technology has almost completely replaced conventional retaining structures. Geogrid Reinforced earth wall retaining structures have gained wide acceptance in India as a technically proven and cost effective alternative to conventional concrete retaining wall. The ongoing and planned initiatives of central and state governments for improving the road infrastructures in the country are likely to give a major boost for the demand for Geogrid reinforced wall systems. Geosynthetics have become well established construction material for geotechnical and environmental applications in most parts of the world. Results from recent research and from monitoring of instrumented structures throughout the years have led to new design methods for different applications of geosynthetics. The geosynthetic reinforced soil has emerged in the last few decades as a technically attractive and cost effective solution to many geotechnical problems. This concept was used for the construction of vertical wall in the Outer Ring Road of Hyderabad in the stretches from Patancheru – Mallampet from Km 23.700 to 35.000 with segmental blocks as the facing elements.
