Abstract:

The design and performance of reinforced soil structures is significantly influenced by the fill material. Particularly, reinforced earth retaining walls require frictional fills as they are free draining and mobilize higher friction coefficients with reinforcing elements. The frictional fill materials to be used in reinforced soil structures are river sand and moorum. Due to increased construction activities, the sources of sand and moorum are depleting at faster rate. Hence, the search for alternate fill material for use in reinforced soil structures has arised.
