‘Zero-emission’ German technology mastic asphalt for Red Road

Red Road, which served as a British airstrip roughly for three years during World War II, will get its top cover re-laid with a layer of mastic asphalt which will be prepared using a ‘zero-emission’ German technology.

A plant located near Rajarhat that uses the new German technology will produce the mastic asphalt that will be ferried in trucks and laid on the road, engineers said.

The National Green Tribunal had in 2018 banned asphalt baking by the roadside in October 2018.

“This will be the first time that any Kolkata road will get this quality of mastic asphalt,” a senior PWD official said.
