Soil is the origin of everything. As we know everything is dependent on nature, and as a civil engineer we know that soil plays a vital role in construction. When we erect any structure over the soil, firstly we check the behavior and attribute of soil that how much strength is present in the soil so that it can bear structure load which will be erected over this soil. There are several types of soil which have different- different qualities, some soils have greater strength and some have lower, if the strength of soil is lower than our requirement then we constrained to increase the strength of the soil as per our structure requirement. In this research paper we performed various test on soil to know its properties or strength by using agricultural waste material such as wheat husk ash (WHA) as a stabilized material in soil with varying percentages 4%, 8%, 12%,16%. Use of Coconut Coir Fiber for improving soil property is advantageous because they are cheap, locally available and eco-friendly. In this study, the stabilizing effect of Coir Fiber on soil properties has been Experimental studied. Keeping this in view an experimental study is conducted on locally available i.e. expansive soil mixed with varying percentage of Coconut Coir Fiber. Soil samples for California bearing ratio (CBR) tests and UCS are prepared at its maximum dry density (MDD) corresponding to its optimum moisture content (OMC in the CBR mould and UCS sampler without and with Coconut Coir Fiber. The percentage of Coconut Coir Fiber by dry weight of soil is taken as 1%, 1.5%, 2% and 2.5% and corresponding to each Coconut Coir Fiber content soaked CBR tests and UCS tests are conducted in the laboratory. Tests result indicates that soaked CBR and UCS value of soil increases with the increase in Coconut Coir Fiber content. Adding of Coconut Coir Fiber and Wheat Husk Ash results in less thickness of pavement due to increase in CBR of mix and reduce the cost of construction and hence economy of the construction of highway will be achieved. This is because of composite effect of Coconut Coir Fiber and Wheat Husk Ash changes the brittle behaviour of the soil to ductile behaviour.
