Abstract: During the past two decades, the issue of rehabilitation of the existing pavements using various techniques is gaining momentum. The use of fibre reinforced concrete for rehabilitation purposes is becoming popular. Fibre reinforced concrete is an economical method to overcome flexural failure, micro cracks etc. Human hair is a non-degradable fibre which can be used as a reinforcement material in concrete overlays. Human hair fibre added concrete can be used as a concrete for cell filling and whitetopping concrete pavement rehabilitation methods to overcome the functional deficiencies of existing bituminous pavements. In whitetopping a concrete overlay is provided over the existing deteriorated bituminous pavement. In Cell Filled concrete overlay a mesh of cell is provided and is filled with concrete. In this study the mechanical properties of whitetopped and cell filled concrete overlays incorporated with human hair is being investigated. A field trail of Cell Filled and Whitetopped concrete with and without hair fibre was tried. Conclusions were drawn based on these laboratory and field studies.
