For the construction of flyover embankments, the Ministry of Road Transport and Highways (MoRTH) has asked construction companies to promote fly-ash bricks, blocks, and tiles. According to the most recent circular, fly-ash can be used in road construction as long as it meets the Indian Road Congress's standards and specifications. The disposal and use of ash produced by thermal power plants have become a pressing and urgent task. In many ways, using fly-ash in construction will be a long-term solution. The circular also stated that the country generates a lot of fly ash, and a lot of it isn't used, which is a big problem for the environment. This can also be harmful to one's health. In addition to taking up a lot of space, unutilised fly-ash takes up a lot of lands. The increased reliance on thermal power over the years has left a huge hillock of fly-ash at the thermal stations in Karnataka, according to the media. As a result, there was a shortage of available space. The energy department of the state proposed using a variety of technologies to use fly-ash in construction. Within a hundred km of coal or lignite-based thermal power plant, the cost of transportation of ash for road construction projects, manufacturing of ash-based products, or use as a soil conditioner in agriculture activity shall be borne by the coal or lignite-based thermal power plant, according to the circular. It went on to say that transportation costs beyond a radius of a few hundred kilometres, up to 300 km, should be split evenly between the user and the coal or lignite-based thermal power plant. Specifications for the use of fly ash in two, four, and six lane highways, among other things, have been issued by MoRTH. The use of fly-ash for embankment construction is permitted under Section 305 of the Ministry's Specifications for road and bridge works.
