For the first time, Bruhat Bengaluru Mahanagara Palike will use tar sheets on the Richmond Circle flyover, which are said to make the surface more durable.
BBMP chief engineer K T Nagaraj said the sheets, manufactured by Tiki Tar, is weatherproof and would last long. He said Tiki Tar rolls are water bound bituminous emulsions where 25% to 35% water is mixed with the emulsion. These sheets come in rolls, packed in drums. Each drum carries about 20 tar sheets, which cover 120 square metres.
"These brown sheets become black after six hours of laying them. Once the colour changes, we lay a primer and bitumen concrete on them. It gives the bitumen a grip to withstand weather for quite a long time," the engineer said.
BBMP will use these sheets on seven other flyovers, which will be overhauled in the next one year.![]( "BBMP is using tar sheets on the Richmond Circle flyover to make the surface more durable. DH PHOTO")
