Abstract

“In India, roads often suffer from issues such as potholes, cracks, and localized depressions and settlements, particularly during the rainy season. These problems stem from the subgrade soil's insufficient bearing capacity when it becomes water-saturated, with low CBR values of 2-5%. As per the CBR method of pavement design (IRC:37-2012), the pavement thickness increases exponentially as the CBR value of the subgrade soil decreases, resulting in higher construction costs. Therefore, researchers have attempted to enhance the subgrade's bearing capacity by utilizing geogrid materials. Soil samples are tested in the laboratory with and without the inclusion of a geogrid layer, and by altering its position in the mold. The use of geogrid increases the CBR value of the subgrade, reducing pavement thickness by up to 40%.
