Abstract
The concepts of reinforced soil foundation (RSF) have been widely used in various geotechnical engineering applications. Most of the research work has been carried out by making use of frictional soil as a backfill material and fewer attempts have been made by making use of fly ash as backfill material. In the present study fly ash is used as a backfill material. This study highlights the performance of circular footing resting in reinforced fly ash beds under repeated loads. A series of tests were conducted on embedded circular footing resting on polyethylene geogrid reinforced fly ash beds under repeated loading. The experimental results demonstrated that the fly ash can be used as a backfill material in place of any other frictional fill. This is indicated by the higher load carrying capacity of footings resting in fly ash reinforced beds.
