Utilizing the waste tire fibres instead of other types of fibres will serve the dual purpose of utilization of waste as well as improving the behaviour of expansive soils. This paper presents the effect of tire fibres on swelling behaviour of expansive soils with a change in size as well as the percentage of fibres. The consolidation tests were performed and swelling potential was identified and compared for different fibre types A (L/B = 8.95), B(L/B = 6.387) and C (L/B = 4.457) with varying fibre content as 0.25%, 0.5%, 0.75% and 1.00%. The swelling potential for 12 combinations was computed and compared with that of the virgin soil to calculate the swelling potential ratio (SPR) to find out the optimum percentage and aspect ratio at which the fibres are most effective in reducing the swelling behaviour of the problematic soils.
