STABILIZATION OF BLACK COTTON SOIL WITH SAND AND CEMENT AS A SUBGRADE PAVEMENT

The present work is done in stabilizing the black cotton soil by using cement and sand. the tests conducted for this work were atterberg limits, specific gravity , standard proctor test , unconfined compression test , California bearing ratio. All construction should rest on the soil. So, the soil bearing capacity plays a vital role in constructions. All soils will not have good strength and bearing capacity. So there is a need to increase the soil strength and bearing capacity. The black cotton soils pose many problems in construction. So in this present work, the black soil collected from chintakommadinne mandal has been stabilized by using sand and cement. The present work aims at determines the optimum percentage of sand and cement addition to the black cotton soil in improving the strength characteristics of the soil.
