An experimental program was undertaken to study the effect of randomly distributed fibers on the strength properties of highly compressible clayey soil. Improvement in the strength properties of subsoil containing clayey soil used for road construction was obtained by conducting series of laboratory California Bearing Ratio (CBR) test. Series of model footing test was also performed to check the effectiveness of fiber reinforced soil for foundation of buildings. For these study highly compressible clayey soil having CH group and polyester fibers of 6mm and 12mm fiber length were used. It was observed that there is significant increase in CBR value of clayey soil with the inclusion of polyester fibers and due to these increase total thickness of subgrade reduce for the flexible pavement. The results of footing test indicate that due to fiber inclusion there was an increase in the ultimate bearing capacity and reduction in the settlement.
