This paper presents an overview of geosynthetics as a lightweight and sustainable material for wide range of applications in various fields of construction technology in J&K. Srinagar and Jammu are the main two cities-summer & winter capitals of the State, linked by 300km road, which passes through hilly terrain and steep slopes. Due to monsoon and heavy snowfall, there are always chances of landslides, snow avalanches and rockfalls all along National Highway thereby disturbing the normal life. For construction of road in a hilly terrain in J&K, it is necessary to trim the soil on one side and fill the same on the other side to get a level surface. Breast walls and retaining walls are used for stable road formation. But sometimes, in addition to the gravity force on the soil mass, the self-weight of these breast walls and retaining walls add to the instability of slope and the road fails. Thus, there is a dire need for a technically viable, economically feasible, lightweight and sustainable material for use in wider applications. There is a lot of scope for utilization of geosynthetic as a lightweight and sustainable material for construction of roads, rockfall protection, retaining walls, stability of slopes, railway project, erosion control, growth of vegetation, drainage etc., in J&K.
