An Experimental Analysis based Improvement in CBR Value Using Geosynthetic Material

The utilization of modern technologies ensures the durability of the constructed structures in a cost friendly manner. A new building material, reinforced earth was developed approximately 40 years ago. The use of reinforced earth enhances quality of the soil by using Geosynthetic material. Recently, the modern Geosynthetic materials are used extensible due to their robust properties which help to strengthen the soil while using building material. In this work, the tensile strength of a geotextile has been examined on the California bearing ratio (CBR) at different penetration levels in an experimental pavement layer. The impact of geogrids reinforcement on CBR results are studied by adding a layer of a specific geogrids within the sample height. Further, the effectiveness of using unreinforced, all-natural gravel soil is evaluated. Finally, the experiment outcomes reveal the effectiveness of the Geosynthetic material which improves the CBR value for 2.5mm and 5mm penetration up to 5.86 and 6.57 respectively.
