Hi-tech way to speed up road repairs
The use of early strength concrete — a type of concrete that dries up faster as it has added chemicals in comparison to the concrete that is currently in use — has been incorporated in various contracts that are slated to start by October 1mumbai Updated: Sep 02, 2016 23:30 IST
The concretisation cost of roads in the city has gone up by 20-25% — not because contractors bid higher than the estimated cost or because civic officials came up with faulty estimates, but to ease traffic movement.
The Brihanmumbai Municipal Corporation (BMC) has brought in a new technology to reduce the time needed to build new cement and concrete roads to ensure they are opened up for vehicles within 10 days.
The move, however, will add up to the budget for repair and reconstruction of cement-concrete roads.
The use of early strength concrete — a type of concrete that dries up faster as it has added chemicals in comparison to the concrete that is currently in use — has been incorporated in various contracts that are slated to start by October 1.
Civic officials said using the new concrete the road will be ready within 8-10 days, compared to the current 28 days.
A civic official said, “It is a slightly expensive technology. While we spend about Rs800 crore on concretisation of roads every year, we will have to spend Rs1,000 crore on the new technology. It will ease traffic movement at the earliest.”
The civic body will approach the traffic police for permissions to allow 24x7 work on the roads. Currently, the BMC does not allow work to be carried out through the day.
“With this technology, we should have no problem in getting traffic permissions, a process which earlier took us months,” said an official from the roads department, on condition of anonymity, as he is not authorised to speak to the media.
