Innovative environmental friendly new material for the road construction

摘要

An experimental program was undertaken to investigate the improvement in the sub grade soil containing highly compressible clayey soil for the road construction using the polyester fibers as a reinforcement in terms of CBR Value. Reinforcing the soil using the fibers is environmentally friendly innovative techniques because the inclusion of fiber does not affect chemical properties of soil. It was observed that there is significant increase in CBR value with the inclusion of polyester fibers up to 1.5% fiber content for both 6mm and 12mm fiber length. A study for flexible pavement on highly compressible clayey soil reinforced with polyester fibers was also undertaken.
