Nowadays Expansive soils are a worldwide problem for civil engineers. It causes damages to foundations, pavements etc. Due to disposal of plastic waste on soil and pollution, it reduces soil strength and causes various problems on soil. Soil stabilization is the way used to reduce problems in expansive soils. The present project describes about the properties of expansive soil and bottom ash. Bottom ash is used as an additive material for stabilizing the soil. Stabilizing the soil by adding Bottom ash improves the soil strength and reduces swell and shrink. The main aim of this project is to study the effect of bottom ash on expansive soil for road construction. The laboratory tests are carried to determine the index properties and engineering properties of soil sample. The soil samples are prepared with different proportions of bottom ash as 5%, 10%, 15%, 20%, 25%, 30%. This proportion was used for further tests such as Atterberg's Limit test, Standard Proctor Compaction test (SPC), Unconfined Compressive Strength test (UCC), and California Bearing Ratio test (CBR). This project shows that bottom ash improves the soil strength.
