Abstract: | |
Large construction of various Civil Engineering schemes demands optimum and efficient use of construction resources. Requirement of fill material for large-scale constructional activities of roads, is enormous and available soils near construction sites are weak in strength and of high compressibility. This type of low strength soils need addition of some strengthening elements to increase their strength and reduce their high compressible nature. On the other hand, the uses of motor vehicles are increasing in everywhere in an extreme rate. The application of waste rubber tyre in soil results increase in strength and decrease of deformability. Such application will reduce the cost by providing lesser thickness of pavement results lesser quantity of materials. In this paper waste rubber tyre has been randomly mixed at varying length and percentage with weak clayey soil to improve the strength and decrease the deformability of soil. Standard Proctor test and California Bearing Ratio test have been conducted for each combination of soil- rubber tyre chips mix combination to study the behaviour of the engineering properties of soil- rubber tyre chips mix combination. From the test results, it was observed that with the increase in percentage of waste tyre chips in soils, maximum dry density decreases whereas optimum moisture content remains almost constant. Further, the CBR value of the soil- rubber tyre chips mix composite at OMC, increased with increase in percentage of waste tyre-tube chips. |
