Response of Sandy Soil Stabilized by Polymer Additives
Journal Title: Open Access Journal of Environmental and Soil Sciences - Year 2018, Vol 1, Issue 3
Abstract
Traditional sandy soil stabilizers such as lime cement, fly ash and bituminous materials, etc., usually require long curing time. Hence now a day, polymer stabilizer is used more extensively because of its stable chemical property and shorter curing time. For the developing organization, it is important to judge the performance of stabilized soil during its developing stages only. This paper aims to highlight a quick and easy test to evaluate the mechanical performance of such polymer based stabilized soil. For this study, three different kinds of polymer stabilizers at developing stage were evaluated against a market ready product. The analysis of the test result include a comparison of the strength, moisture loss rate and strain energy under different curing time, polymer type, polymer additive amount and test conditions. This study shows that the strength of the stabilized sandy soil is significantly increased both under wet and dry conditions by using the polymer additives. With the procedure mentioned in the paper it was easier to identify the relative merits and demerits of each product. In the desert areas, large amount of soil is lifted by wind, the road is covered by the soil as shown in Figure 1, therefore, soil stabilization is important for road capacity. Soil stabilization is the alteration of one or more soil properties, by mechanical or chemical means, in order to maximize the suitability of soil for a given construction purpose by improving in-situ soil properties. Soils may be stabilized to increase engineering properties like strength and durability; or to diminish erosion and dust generation. The stabilized product should not only enhance desired soil properties, but they should also create a soil material/soil system which can sustain for the design life of the project, under designated load application. In the field application, the polymer dilution is sprayed normally into the loose soil. After polymer dilution penetrates into the soil, compaction of the “wet” soil is carried out. The stabilized soil gains strength after water evaporates from its soil mix. Traditional stabilization of soil relies on cement, lime, fly ash, and bituminous [1-3] material. As the scientists and researchers are developing new engineering materials, many non-traditional materials are available for soil stabilization, for examples polymer emulsion, acids, enzymes and tree resin emulsions [4-7].
