Introduction Civil engineering structures whether minor or huge, modest or complex respites on the ground in which the load of the structure is transferred to soil. Steadiness of any such structure be contingent on the properties of the underlying soil. If the soil strength can be improved by the utilization of waste materials, then the cost of construction can be reduced engineers are faced with the maintenance of structures with the use of limited finance (O. S. Enokela, 2012). Structures such as roadway project and building practices require first- class material for completion of building standards Superiority material is unattainable or in short supply ng several areas of the world. Due to these restrictions, engineers are often involuntary to seek other design using substandard resources which is costly, marketable building aids, and novelty design performs. Certain innovative energies are complete to reinforce the sub grade soil by mechanical stabilization or soil-cement, lime and etc to improve its performance. One of the latest techniques is the soil reinforcement (M. Parag Chaple, 2013). Soil strengthening is an active and dependable technique for refining strength and stability of the soil This project focusses on the available materials that is available in Fiji the soil improvements by mechanical stabilization may consist in the use of Coir or coconut Fibre and bamboo fibres (P. K. Jayasree, 2015). So, this coir Fibre excess can be used in stabilization of soil and thus it can be efficiently disposed of (Stuti Maurya, 2015). The inclusion of fibres had some influence on the engineering behaviour of soil-coir mixtures. The accumulation of arbitrarily spread polypropylene fibres lead to in considerably plummeting the consolidation settlement of the clay soil. Span of fibres has an immaterial

Adding of Fibre give rise to in decrease in plasticity and intensification in hydraulic conductivity (Dharmendra Kumar, 2015). Since there are many types of fibres readily available in Fiji such as coconut husk, bamboo etc... utilizing this fibre as soil stabilizing components which is an advantage to cost and are environmentally friendly. 2. ResearchProblem and Objectives Objective The chief objective of the project is to study the effect of the soil strength after the application of sustainable soil stabilization methods and materials. Statement of the problem (Anon., n.d.) This research focuses on soil stabilization materials and methods thereby soils and related materials and structures are made stronger. It is seen in Fiji that for retaining walls, pavement and other construction works, reinforcement steel is used in massive quantities and the cost of which is very high. Therefore, instead of using tones of reinforcement steel , we can simply replace it by using geotextiles and geo-synthetic materials, or we can use other methods which will be sustainable and effective. 3. Methodology Many natural resources are used and wasted with price in construction of building and structures. The use of sustainable materials in the roads and foundation design of buildings is counseled. A sequence of model test will be done on both road model and foundation model that will be approved purchasable by means of the model test facility that will be developed at the geotechnical laboratory, Department of Civil engineering, FNU. The collection of data will be achieved from the site and the experiments done in the laboratory. Logical data from the testing of soil will be obtained to do analysis in GeoStudio software. The results obtained from the testing will be accumulated to be used in FLAC 3D. Experimental arrangements, testing apparatus, sizes and experimental process will be established on the source of objectives and probable results of this study. 4. Expected outcomes The following specific outcomes may be expected from this research: Explaining the mechanism of sustainable stabilization of soil Working on model dimensions and experiment testing preparations Using of Geo-studio software for modeling and analysis for results
