In this present study was to assess the effect of waste industrial materials i.e. marble dust and fly ash to enhance the index and engineering properties of expansive soil. The physical and chemical properties of soil were improved by the addition of such materials. The obtained result has been carried out for the properties like index properties, Compaction characteristic, and Strength characteristic. Expansive soil covers about one-fifth of the total area of India, particularly in the states of Gujarat, Maharashtra, Madhya Pradesh, Karnataka, Rajasthan, Andhra Pradesh, Telangana, and Tamil-Nadu. Expansive Soils Contain clay minerals that captivate and absorb water. As conclusion, these soils expand when they get wet and shrink when they dry. The Volume changes the experience by expansive Soils can cause serious damage to concrete foundations and floor slabs. Fly-ash is a byproduct dumped out of thermal power plants that use coal as one kind of fuel. Current annual production of fly ash, a byproduct from coal-based thermal power plants (TPPs), is about 112 million tones (MT). Marble dust is generated during the cutting process of marble. India is estimated to have 3,172 thousand tons of marble dust was produced in a year. The marble dust and fly ash in Expansive soil is 10%, 20% and 30% by weight and comparison of the properties of expansive soil with the subgrade stabilized the soil. This study is to explore the favorable reuse of industrial materials i.e. marble dust and fly ash in soil stabilization. Atterberg limits, OMC and MDD, California Bearing Ratio (CBR), swelling pressure tests were performed on natural and proposed soil samples. Measure the results obtained of the natural and treated samples, the CBR increases by 250% (when 30% marble dust and fly ash are added) and the swelling reduction of 58% is found, depending on additive content. The results conclusion shows that the modification of expansive soils by fly ash and marble dust admixture is successful and more economical.
