Marine Clay Stabilisation using an Encased Stone Column Filled With Tyre Chips as Aggregates-Video

Video Transcription

Video Summary

Naxivaji Polisetti presents an experimental study on using recycled tyre shreds as partial substitutes for stone aggregates in geotextile-encased stone columns. Model tests in soft clay compared load–settlement behavior across different replacement ratios. Stone columns improved the clay’s load capacity, while geotextile encasement reduced bulging and settlement. Load efficiency remained above that of a conventional stone column up to 60% tyre-shred replacement, but practical and settlement considerations led to a recommended optimum of 40% replacement for encased columns. The approach could reduce aggregate use while repurposing waste tyres.
