The civic body will be purchasing three such machines for ensuring speedy repairing of potholes.

The standing committee on Monday approved the purchase of three new machines to repair potholes costing Rs 2.34 crore. The truck mounted machines will use cold mix emulsion (called Carboncor) to fill and repair the potholes and trenches. The machines will fill and repair the potholes speedily and effectively and will be operational in eastern, western suburbs and the city area.

Potholes caused by heavy rainfalls are usually filled manually by labourers by mettle and grit. However, this technique does not work long term and results in spilling of grit and mettle on roads and bumps.
