摘要：

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. The inclusion of anchors in the geogrid results in enhancing CBR value for the reinforced condition to a percentage improvement of 95%. (c) 2021 Elsevier Ltd. All rights reserved.
