In India millions of tons of red mud are produced from alumina industries. Its property is similar to sandy clay and it mainly comprises of oxides of aluminum, iron and silicon. Its storage has created enormous problems. To solve this problem alternate uses of red mud should be investigated. Improvement of load bearing characteristics of red mud with the help of geogrid is presented in this paper. This reinforced red mud will be useful as pavement materials for roads, particularly in areas nearer to alumina industries. This paper presents laboratory test, particularly soaked California Bearing Ratio test conducted on unreinforced and red mud reinforced with single geogrid layer. CBR test results are compared for reinforced red mud by varying the embedment depth of geogrid layer. Consequently, it is concluded that according to load bearing criteria optimum embedment depth of geogrid is equal to diameter of CBR loading plunger.
