Geosynthetic Materials and its Properties for Reinforced Earth Structures

The national planners have put infrastructures development on priority. This has resulted in transport planning widening of National Highway and new roads in country. Thus work of Retaining Earth (RE) structures/ slopes will be going to design in very large numbers over different areas. The availability of backfill material compatible with geosynthetics reinforcements and economy in both has been topic for R & D. The conventional reinforcement with facial block element based on BS 8006:1995 was reviewed in brief. Then the options for alternative fill materials such as wastes soil and Ash with modern woven geofabrics of different raw materials are explained in general. The work in progress, primafaci suggest studies to adopt polyester woven fabric with better strength with creep consideration, UV stability, permeability control, economy and easy of construction. Overall effect is to evolve appropriate code of practice for design and construction in areas having CH (high plastic clay) soil, waste material for site where land is economically easily available.
