Abstract: India is sixth largest electricity generating and consuming country in the world. The rapidly increasing demand for energy in India leads to commissioning of new thermal power plants. Coal is the main fuel resource of these power plants. But Indian coal has about 30-40 % ash content. Disposal of ash, particularly fly ash is an environmental issue and is considered as waste material if it is not effectively reused. Surface mines displace huge overburden material as abandoned waste. Often the cost of production increases due to poor haul road. So an attempt has been made to use those mine spoils with fly ash as road construction materials. This paper presents characterization of fly ash and over burden materials. Composite materials have been developed with additive. Unconfined Compressive Strength, Brazilian Tensile Strength and Ultrasonic pulse velocity test results are reported. Tests were carried out with different percentages of Clinker (2%, 4% & 8%). The Scanning Electron Microscopy (SEM) is done in order to show surface image of cured composite materials stabilized with clinker.
