The BBMP, which has resumed repairing broken roads after a long gap, plans to use the micro-surfacing technology to improve the motorability of six stretches.
The new method of road repair, touted to provide a smooth road surface, involves a mixture of just three to six millimetres of bitumen aggregate along with asphalt emulsion. Each kilometre of micro-surfacing is estimated to cost Rs 15 lakh, which is three times cheaper than the traditional method of road repair that uses bituminous concrete.
While experts hail the micro-surfacing technology, the BBMP’s list of roads that will undergo repair includes some stretches that are in good condition. These roads are proposed for development using the grants earmarked under the 15th Finance Commission.
