Earth has been used for building for thousands of years throughout the world spanning a diverse range of climates and cultures. Earth itself is a multicomponent system usually consisting of stones, sand, silt, clay, water and, near the ground surface, organic humus. Structural stability of earth buildings is maintained by the structural integrity of the sand and stone framework, by the pore filling capacity of the silt and most importantly, by the binding qualities of the clay, which are in turn influenced by the moisture content of the soil. Compared with some building materials earth can be considered to have some disadvantages – it has relatively low compressive strength, tensile strength and abrasion resistance. It may also lose a lot of its rigidity in the presence of water. Nevertheless, it is very cheap, very widely available, environmentally friendly, strongly linked to local cultures and traditions and, with skillful construction, can contribute significantly to the aesthetic appeal and user comfort of buildings. In the present study attempt has been made to increase the strength of soil. In this research paper we performed various test on soil to know its properties or strength by using agricultural waste material such as Fly Ash as a stabilized material in soil with varying percentages 10%, 20%, 30%,40%. Use of Sisal Fibre for improving soil property is advantageous because they are cheap, locally available and eco-friendly. In this study, the stabilizing effect of Sisal Fibre on soil properties has been Experimental studied. Keeping this in view an experimental study is conducted on locally available i.e. expensive soil mixed with varying percentage of Sisal fibre. 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 Sisal fibre. The percentage of Sisal fibre by dry weight of soil is taken as 0.25%, 0.50%, 0.75% and 1% and corresponding to each Sisal fibre 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 Sisal fibre content. Adding of sisal fibre and Fly 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 sisal fibre and Fly Ash changes the brittle behaviour of the soil to ductile behaviour.
