| description | The vertical stress exerted by the vehicles will be high in a populated road and to increase the bearing capacity of subgrade characteristics, geosynthetic material can be used. In the current study different geosynthetic material such as geo-grid, geo-textile and geo-membrane were used to as a subgrade reinforcement member inside the CBR mould for understanding the improvement in subgrade for single, two and three geosynthetic layering in the CBR mould. The results show there was a constant increase in the bearing with the increase in a number of layers and this improvement varied with type of geosynthetic materials also. Among three geosynhteic materials, geogrid shows improved CBR characteristics. Finally, Cost analysis and design of flexible pavement were carried for an optimum number of layers for geogrids. There was reduction of about 6.38% in the cost of construction when using geogrid as subgrade reinforcement member. |

La tensión vertical ejercida por los vehículos será alta en una carretera poblada y, para aumentar la capacidad de carga de las características de subrasante, se puede usar material geosintético. En el presente estudio, se usaron diferentes materiales geosintéticos, como geo-rejilla, geo-textil y geo-membrana, como elemento de refuerzo de subrasante dentro del molde CBR para comprender la mejora en subgrado para capas simples, dos y tres geosintéticas en el molde CBR. Los resultados muestran que hubo un aumento constante en el rodamiento con el aumento en varias capas y esta mejora también varió con el tipo de materiales geosintéticos. Entre los tres materiales geosintéticos, la geomalla muestra características CBR mejoradas. Finalmente, el análisis de costos y el diseño de pavimento flexible se llevaron a cabo para un número óptimo de capas para geomallas. Hubo una reducción de alrededor del 6.38% en el costo de construcción al usar la geomalla como miembro de refuerzo de subrasante.
