Abstract Geosynthetic reinforcement is one of the techniques adopted to improve their performance in pavement design.Geogrid are single line and multi-layer materials usually made by extruding and stretching high density polyethylene,or by weaving or knitting and coating high-strength polyester yarns.The resulting lattice structure has large holes that improve interaction with the soil aggregate. Roads having mostly the problems like the formation of potholes, ruts, cracks and localized depression and settlement, especially during rainy season. These are mainly due to the insufficient bearing capacity of the subgrade in water saturated condition.Geogrids are reinforcing elements to strengthen the ground in order to work on very soft and weak ground in the construction of asphalted or unpaved vehicle roads and areas where the high traffic flow is expected.Laboratory and simulated field CBR tests are conducted on soil samples with and without the inclusion of geogrid layer and also by varying the position of it in the mould. Use of geogrid increases the CBR value of the subgrade and thereby reduces the pavement thickness considerably up to 40%.This study will have positive impact as it will be reduce both project and road maintenance costs.
