We have seen the non uniformity, non consistency, loose soil, unstable soil while construction of roads. We have experimentally examined that geogrid can be added as an additional reinforcement. The benefit of Geogrid is that the geogrid increases the bearing ability of construction and reduces the spreading of gravels and soil. The Geogrid is also economical so the cost of construction can be reduced. Geogrid gives strength to the construction and increases life span of construction. Geogrid reinforcement is a method used in permanent paved roadways in two major application areas. They are: base reinforcement and subgrade stabilization. The strength and life of pavement is greatly affecting the type of sub- grade, sub base and base course materials. But in India most of the flexible pavements are mainly constructed over weak and problematic sub-grade. In base reinforcement, the geogrids are placed at the bottom of unbound layers of a flexible pavement system and improve the load-carrying capacity of the pavement under repeated traffic. In subgrade stabilization applications, the geogrid is used to build construction platform over weak subgrade to carry equipment and facilitate the construction of the pavement system without over deformations of the subgrade.
