Abstract: | |
Due to large-scale constructional activities of roads in India, requirement of fill material is enormous and available soils near construction sites may be weak in strength and of high compressibility, even after proper compaction. Such soils need addition of some strengthening elements to increase the strength and to reduce the compressibility of weak soil. On the other hand, the uses of plastic waste bags are increasing in everywhere in an unprecedented rate. Huge stockpiles of scrap or waste plastic bags constitute environmental and health hazards by producing air pollution from waste plastic stockpile fires and breeding grounds for potential disease. Also scrap waste plastic does not decompose easily. In such conditions, clayey soil mixed with randomly distributed waste plastic bags can be used if suitable, to increase strength and decrease deformability in road construction in a cost- effective manner. This paper presents the stabilization of cohesive soil using randomly distributed waste plastic bags at varying lengths and percentages by weight of cohesive soil. Compaction tests were conducted to investigate the behavior of clayey soil mixed with waste plastic bags. From the test results, it was observed that with the increase in percentage of waste plastic bags in clayey soil, maximum dry density decreases whereas optimum moisture content increases. But, the strength values of the composite at OMC, increased with increase in percentage of waste milk plastic bags up to a certain limit. |
