As for as flexible pavements are concerned concrete pavements are more durable, while requiring less maintenance and having longer life. This paper discusses about the benefits of rigid pavements utilizing bamboo fibre. The study aims to investigate the feasibility of using bamboo as a fibre in pavement quality concrete with different water/powder ratios by adding bamboo fibre. This research presents the detailed amount of fibres used in the pavement quality concrete on trial basis. Since the strength and stiffness of natural fibre concrete reduces with time, adequate precautions should be taken when using natural fibre. To prevent the decay of fibres, the partial replacement of cement with mineral admixture is being recommended. Also using mineral admixtures makes concrete less permeable and less the permeability more durable the concrete is. Bamboo with high percentage of sugars(4.92%)
having retarding effect on the setting and strength development of cement matrix should be kept in concentration and to overcome that, addition of chemical admixtures is necessary to counteract the adverse effect.
