Improvement of California Bearing Ratio value in weak subgrade soil with the developed anchored geogrid

This study aims to improve the California Bearing Ratio (CBR) value of the weak subgrade soil using a modified form of geogrids with anchors. The tests are carried out with a single layer of geogrid as reinforcement to determine the optimum placement depth in the CBR mould. The modified geogrid with anchors positioned at the optimum placement depth for which the CBR value is 6.00 compared to the CBR value of 4.68 for the reinforced condition....
