The performance of a pavement is very responsive to the characteristics of soil sub grade. The economic design of pavement results in saving countries economy. The construction of roads in most of the places across the world faces major problems due to weak sub grade soil. Sub grade being the support for the whole pavement, it needs the utmost care in its construction. During last few decades� research has been conducted on various aspects of low volume roads resulting in innovative and unconventional approaches of road constructions. Many suggestions have been put forward by various scientists to improve the subgrade.Usually adopted methods are stabilization methods. Use of waste material and natural fiber for improving soil property is advantageous because they are cheap, locally available and eco-friendly. In this study, the stabilizing effect of Natural fiber (coconut coir) and ceramic waste powder on soil properties has been studied. Over the last decade the use of waste material and fiber has recorded a tremendous increase. Keeping this in view an experimental study is conducted on locally available i.e. clayey soil mixed with varying percentage of coir fiber and ceramic waste powder. Long term performance of pavement structures often depends on the stability of the underlying soils. Conventional waste disposal methods are found to be inadequate. The existing soil at a particular location may not be suitable for the construction due to poor bearing capacity and higher compressibility or even sometimes excessive swelling. For sustainable development use of waste material should been encouraged.It is crucial for highway engineers to develop a sub grade.
