Development of dune sand by the inclusion of geotextile layers
The present study proposes the use of dune sand, reinforced with geotextile, as roadway layer. The investigation aims to evaluate the convenience of the reinforced sand, with a view to face of the scarcity of used materials, and also for socio-economic development in northern-Africa Sahara regions. The analytical approach is totally experimental and is based on the California Bearing Ratio (CBR) test procedure. The obtained results are interpreted with referring to bearing of a foundation soil. These indicate that inclusion of single geotextile liner increases the sand CBR value by 73%. The inclusion of two geotextile layers increases this ratio more than 6 times. This makes the sand to pass from a low bearing material to a good supporting novel composite product. The study highlights the advantage of implementing geotextile sheets comparing to geocell reinforcement, as well as the manifest of slab-effect by the confined sandy layer. Furthermore, the soil layer depth beyond which the geotextile contribution becomes insignificant is pointed-out, as well as the sandy layer supporting the applied load.
