Abstract:

The performance of flexible pavement depends mainly on the subgrade soil characteristics as it serves as a foundation for pavement. Roads constructed over poor subgrade soil i.e. soil having low California bearing ratio and undrained shear strength values fails frequently leading to heavy economic burden apart from high initial cost of construction because of thicker layer of aggregate base and sub-base. In order to overcome these problems soil reinforcement technique has to be adopted. The use of geosynthetic material is a new and emerging technique and is gaining importance due to cost and time saving apart from less environmental sensitive nature and is consistent over a wide range of soils. In the present study an attempt has been made to make use of non-woven geotextile and biaxial geogrid in various combinations. The geotextile and geogrid was selected from the list of materials accredited by Indian Roads Congress. The geogrid was placed above geotextile, both in layers from the top of mold and heavy compaction, soaked CBR and unconfined compressive strength (UCS) tests were performed as per relevant parts of Indian standard code (IS: 2720).
