Tyre fibre being one of the wastes generated during the tyre rereading process is a sustainable material to improve soil shear strength. A few studies are available where tyre fibre is used to increase the soil strength. The present study seeks to evaluate the impact of scrap tyre-derived fibres on the strength characteristics of lateritic soil. Tyre fibre is added with 0, 1, 2.5, 5, 7.5 and 10% of dry weight of soil. Compaction test was done for the six mixes of soil and tyre fibre and it was found that the maximum dry density decreases with the increase in tyre fibre. Direct shear tests were performed on compacted specimens to study the shear strength parameters of different mixes of soil. It is seen that tyre fibre when reinforced with lateritic soil, shear strength increases. The friction angle increases with the increase in tyre fibre. At 7.5% tyre fibre content, soil mixes show the highest values of friction angle.
