Speaking at the BBB Summit here, the minister said the two ministries had a meeting last month on the use of lignin in Bitumen. “Now CRRI has implemented a successful project where lignin is added 35 per cent in Bitumen. Using this, we have already completed 1 Kilometer of road laying in Nagpur – Jabalpur road. CRRI has certified that it is 50 per cent better than petroleum Bitumen,” Gadkari said.
