Enhancing the Properties of Soil using Plastic Waste

Soil stabilization is the methods of improvement of the engineering property of the soil and thus making more stable. Soil is not suitable for construction purpose. In its broadest Sense, stabilization includes compaction, preconsolidation, drainage and many other such processes. Soil stabilization is generally restricted to the processes which alter the soil material itself for improvement of its properties. The construction work is needed for all time low cost material and environment sociable and suitable for construction work. Road are such as important key of connectivity in India and Highway Roads are always a need low cost material and maintenance free roads. Due to smaller availability of fund use of waste material from industries and agricultural fields is much in use. This practically work in brief describes the use of locally available waste plastic in soil stabilization. Stabilization of soil using plastic waste strips is an economically and easy methods to dispose the plastic waste. Due to increase of population and urbanization and also increase the production of plastics material but recycling of these plastics is a smaller amount compared to its production. In present work the plastics is made in to strips mixed with black cotton soil is studied carrying different test on black cotton soil. The plastics strips are added by different proportion by dry weight (1.0% to 5 %) of the soil. The soil sample used is clay which requires to be strengthened due to presence of high plasticity, this soil sample is strengthened by using varying proportion of plastic. Various tests were conducted to analyze the effect of plastic strips on optimum moisture content, maximum dry density, unconfined compressive strength and California bearing ratio. From the results increase the maximum dry density and decrease the optimum moisture content, Along with increase in unconfined compressive strength and California bearing ratio, from the observations it can be seen that 3% of plastic strips results in maximum improvement in desired soil properties. Due to its low cost and effectiveness in increasing the California bearing ratio of soil this method of soil stabilization is strongly recommended In this practical work the increase the strength and CBR value of added a plastic strips. These methods are useful for different pavement and most usefully for village road and also reduced pavement thickness of the road.
