Bengaluru: The Bruhat Bengaluru Mahanagara Palike (BBMP) has taken up re-laying roads with ‘Tiki Tar’ sheets at HBR Layout at an estimated cost of?Rs 1.14 crore. The BBMP had used this technology to asphalt the Richmond Circle flyover recently. The civic body decided to opt for the tar sheet asphalting technology in a bid to make the road surface more durable and weather-proof.

Under the new technology, asphalting work is carried out by laying ‘Tiki Tar’ sheets that are water-bound bituminous emulsions. These sheets come in rolls, packed in drums. These brown sheets become black six hours after they are laid. Once the colour changes, primer and bitumen concrete are poured on them. The sheets are manufactured by Mumbai-based Tiki Tar Industries.

According to BBMP sources, around 570 metres of the stretch from BDA Complex, HBR Layout 2nd Block to the corner of Tannery Road will be laid with tar sheets.

The BBMP sources said that other flyovers too would be upgraded with tar sheets soon and they are in the process of identifying prominent flyovers across the city.
