Introduction Among several innovative construction techniques, new materials of constructions and new technologies adopted in the construction of flyovers in many places, the reinforced earth technique has definitely proved the advantages of this technology over conventional reinforced concrete (RC) retaining walls both in terms of saving foundation cost, working space and time(Chonkar, 2001)[1].
Andrawes and Saad (1999) [4] reported that a vertical compressible layer between the facing and the backfill material could significantly reduce the horizontal stress acting against the back of the facing.
