This research focuses on the placing of special type of soil reinforcing material called as Composite Geotextile (CGT) in the red laterite soil for the improvement of the strength properties like California bearing ratio. In this study this CGT was placed at different depths from the top of the surface and the CBR values are studied in the soaked and unsoaked conditions. At the depth ratios of 0.25 D, 0.5 D and 0.75 D these CGTs are placed in a CBR mould and Load tests are conducted. The results show that the CGT layer has a significant effect on the behaviour of laterite soil, such as load carrying capacity and the efficiency of the reinforcements. Reinforcing with CGT resulted in a substantial increase in strength of the soaked and unsoaked samples due to confinement of stone dust layer between geotextiles, it act as a strong reinforcing material. In this article, the load-penetration characteristics and CBR values of unreinforced and reinforced lateritic soil during the loading process are examined.
