Nagpur: The Nagpur Municipal Corporation (NMC), in order to overcome the nagging handicap in asphalting roads during rainy season. Now, the local body is planning to procure micro surfacing road asphalting technology machine which can asphalt the road even in rainy season. Such asphalted roads withstand the accumulation of water. NMC will be the first civic body in Maharashtra if it deploys the machine. The only authority engaging the machine is National Highways Authority of India (NHAI) for repairing national highways for last six years.
City-based Anjani Logistics, operator of road jetpatcher, gave a demo of the machine a couple of days ago by asphalting a 100 metre stretch on RPTS Road between Surendra Nagar and Ajni Square. Mayor Pravin Datke, Municipal Commissioner Shravan Hardikar, Chief Engineer Ulhas Debadwar and other engineers from NMC witnessed the demo. Debadwar said the machine can be beneficial for NMC in various manners. It is also a cold mix technology.
The best part is that polymer is used in it. Hot mix tar is destroyed when water accumulates on it. Polymer prevents seepage of water into the road. Therefore, life of road increases with this technology, he said and added the machine can be useful in case NMC borrows it and operates it on its own.
Narendra Jichkar of Anjani Logistics said the cost of road asphalting reduces by 50% in the technology. “Hot mix tar costs 400 per sq m while micro surfacing costs only 200 per sq m. Layer of 40-50mm is laid in hot mix while only 4-6mm is laid in micro surfacing. It saves cost and also nature, since lesser material is required, and also does not result in increase in the height of roads,” he said. The machine is from Germany and costs around Rs 3.50 crore. Another issue is that the adhesive used in the technology is available only in Germany.
