Abstract
The performance of any reinforced soil structures is primarily governed by soil and geosynthetic interface friction mechanism. Nowadays, due to non- availability of suitable backfill materials, exploration has been started to find out alternative one. On other hand, pond ash which is a waste by-product generating from thermal power plants has many desirable engineering properties, encouraging to use as backfill material. In this connection, the present work is focused to find the interfacial frictional characteristics of pond ash reinforced with two biaxial geogrid materials by conducting the large scale direct shear test and pullout tests. From the test results, it is observed that the interface friction properties of two tests in terms of coefficient of interface friction (\( \text{C}_{\text{i}} \)) and pullout frictional factor (\( \text{f}^{*} \)) are in the range of 0.86 to 0.74 and 0.54 to 0.35 respectively.
