Geogrids are single or multi-layer materials usually made by extruding and stretching high-density polyethylene or polypropylene, or by weaving or knitting and coating high-strength polyester yarns. The resulting lattice structure has large holes (called holes) that improve interaction with the soil or aggregate. Due to their high tensile strength and stiffness, geogrids are particularly effective as soil and aggregate reinforcement. . Roads in India mostly have problems like formation of potholes, ruts, cracks and localized depressions and settlements especially during rainy season. The reason is primarily the insufficient bearing capacity of the subsoil in a state saturated with water. The subgrade usually provides a low CBR value of 2-5%. In the CBR method of pavement design (IRC:37-2012), the total pavement thickness increases exponentially as the CBR value of the subgrade decreases, which in turn increases the cost of construction. So it was tried to use the geogrid material to increase the bearing capacity of the subsoil. Laboratory and simulated field CBR tests are performed on soil samples with and without by including a geogrid layer and also changing its position in the form. Use the geogrid increases the CBR value of the base and thereby reduces the road surface thickness significantly up to 40%. This study will have a positive cost impact as it will reduce both project and road maintenance costs.
