Critical Appraisal on Utilization of Geocell for Improving the Unpaved or Earthen Shoulder

Abstract

This research paper describes the founding of different research paper published so far worldwide on use of Geocell in road construction. Geocells are three-dimensional, honeycomb-shaped soil-reinforcing geosynthetics composed of polymeric materials and are primarily used for confinement of granular material. Geocells are placed at sub base, in-filled with soil material, and compacted. The cellular structures of the geocells provide lateral and vertical confinement and tensioned membrane effect, thereby increasing the bearing capacity and providing a wider stress distribution. As a result, rutting or permanent deformations under traffic loading can be reduced. India has one of the world’s second largest roadway network transporting millions of people every year and also has heavy road traffic condition. Due to heavy traffic condition in India, heavy loading vehicles and other vehicles use pavement shoulder for passing or overtaking operation. Pavement Shoulder is made for some particular uses but heavy loading vehicle in one or two lane road use shoulder for pass away so that rutting of pavement shoulder happened. So it is necessity to improve strength, erosion control, and durability of shoulder for safety of road users for that we use geocell material at sub base or base layer of shoulder for giving better strength and it is also economical.
