Abstract
Roadways with expansive clay subgrades and exposed to environmental pressures have lately seen the usage of geosynthetics for base course stabilization. The environmental longitudinal fractures that develop as a consequence of differential settlements between the highway sides and its centerline are a direct outcome of the substantial and uneven variations in moisture content that occur within clay subgrades as a result of seasonally wet and dry cycles. Quantifying the field performance of several sites, this article evaluates the efficacy of geosynthetics in stabilizing the base course of highways built on expansive clay subgrades. The assessment includes five complete field projects that were tested under real-life traffic and environmental conditions. By measuring the occurrence and severity of longitudinal cracks as well as the reduction in base course stiffness, the long-term performance of both the geosynthetic-stabilized and control sections could be assessed. The subgrade's property determines the road's performance. Soil stabilization using locally accessible geosynthetics is the subject of this research. Here we see Geotextiles and Geogrid put to work as geosynthetics. Soil was compacted to an ideal moisture content and maximum dry density before CBR tests were carried out. On the same soil that was reinforced with different types of geosynthetics, the changes in CBR value were examined. Therefore, the study aims to recommend the best cost-effective and performance-enhancing geosynthetic for subgrade stabilization.
