Geo-textile used to repair NH-8

Geo-textile technology is being used for the first time to repair damaged parts of NH-8 in Assam’s Karimganj district. Repairing work is going on a war footing to improve the stability of the soil for all-weather road that leads into Tripura.

Geo-textiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect or drain. Typically made from polypropylene or polyester, geo-textile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt) and heat-bonded (resembling ironed felt).

Geo-textile composites have been introduced and products such as geo-grids and meshes have been developed. Overall, these materials are referred to as geo-synthetics and each configuration—geo-nets, geo-grids, geo-tubes (such as TITAN Tubes) and others—can yield benefits in geo-technical and environmental engineering design.
