India has set the Guinness World Record with World’s Longest Steel Slag Road at Raigarh in Chhattisgarh. The 1.85-kilometre road marks a major scale-up of an indigenous technology that converts processed steel slag, a by-product of steel production, into aggregates for road construction.
Speaking at the conferment ceremony of the Guinness World Record in New Delhi today, Science and Technology Minister Dr Jitendra Singh said that Steel Slag Road Technology can reduce road construction costs by around 40 per cent while delivering four times the strength of conventional roads. He said that this technology is being pursued by CSIR-Central Road Research Institute (CSIR-CRRI) New Delhi with private sector participation.
Dr Singh said that this initiative simultaneously lives up to more than one flagship priorities of this government emphasising on Waste to Wealth recycling options. He said that the technology can also substantially extend the maintenance cycle, with a re-look required only after about 15 years in suitable applications, making it a breakthrough with implications not only for road engineering but also for the overall infrastructure economy.
The Minister called for the indigenous technology to move from one project to many projects and from one State to many States, with its adoption extending beyond the Ministry of Road Transport and Highways to Railways, other Government departments, State Governments and private builders.
