Behaviour of Natural Fibres in Rigid Pavement

Concrete is weak in tension and has a brittle character. The concept of using fibres to improve the characteristics of construction materials is old. Early applications include addition of straws to mud bricks, horse hair to reinforce plaster and asbestos to reinforce property. The modern development of fibre reinforced concrete (FRC) started in the early sixties. Addition of fibres to concrete makes it a homogenous and isotropic material. When concrete cracks, the randomly oriented fibres start functioning, arrest crack formation and propagation, and thus improve strength and ductility. The objective of this study is to investigate the effects on stress development in pavements and on critical design factors substituting natural fibre reinforcement for conventional steel reinforcement in pavements to determine the performance characteristics of the natural fibre reinforced concrete pavements. the result of this study target the design of pavement with natural fibres. They propose feasible natural fibre design to be constructed. The natural fibres reinforce the concrete as much as steel reinforcing does in conventional concrete. This results in product with higher flexural and tensile strength than normal concrete, allowing its use in thin-wall casting applications. NFRC is a light weight, durable material that can be cast into nearly unlimited shapes, colours and textures. This project includes various tests on soils, aggregates and various concrete tests and mix design for each layer of the rigid pavement. NFRC is a specialized form of concrete with many applications. It can be effectively used to create faade wall panels, fireplace surroundings, vanity tops and concrete countertops due to its unique properties and tensile strength. One of the best ways to truly understand the benefits of NFRC is a unique compound.
