Bangalore roads may soon wear a brand new look, if the Bangalore Mahanagara Palike has its way.

The BMP is set to venture into a cost-effective initiative that promises to give the much required strength to our roads.

The BMP will use a Mobile Cold Recycling Mixing Plant from Germany and the technology will be provided by a company called Wirtgen Groups. According to Mr Charmanna, Manager, Service and Product Support of Wirtgen Technologies this advanced technology is better than the conventional road laying methods because very little extra material (cement and bitumen) is used.

Elaborating, Mr Charmanna said three separate machines – millers (scrapers), mixers and layers – would be used. The existing road will be scraped off as per the required depth (about 160 mm) by the miller and it will be transferred through conveyors onto hand carts.

This is where the cost effective bit comes in, because, the scraped material will be reused. It will be mixed in the mixer along with foam bitumen and cement. This will then be transferred to the layer that will lay the mixture on the road.

“Presently roads are asphalted along existing cracks which will eventually lead to more cracks, with the road wearing out within a year. But, we will ensure that the base of the road is stronger by digging and laying the road on an even surface, the roads will then stand good for more than eight years,” said Mr Charmanna.

Indiranagar 100 feet road will be the first to be experimented on.
