Abstract:
Soil stabilization is the process of improving the load bearing capacity and engineering properties of subgrade soil to support pavements and structures. This work examined the stabilization of two soil samples (with geotextile & without geotextile). CBR were conducted with and without geotextile. Geotextile were placed at various depths (top & bottom, middle, 1/3, 1/4). The experimental results give a clear indication that the presence of geotextiles increases the CBR value of the soil thus, geotextile should be employed as a modernized form of improving road construction on poor soils and to reduce the layer thickness of pavements.
Key words: stabilization, geotextile CBR, pavement, soil.
