The standing technical advisory committee (STAC), in its meeting on Thursday, ordered the Brihanmumbai Municipal Corporation (BMC) to use a special material – mastic asphalt – to ensure pothole-free bridges and flyovers.
Claiming that the material could help in making the roads better, the STAC has directed the authorities to use mastic asphalt to resurface the 34 dilapidated bridges in need of urgent repair and flyovers in the city. The committee will also inform other road development bodies such as MMRDA and MSRDC to use it.
The committee has also instructed the civic body to check the four technologies – currently being tested to fill city’s potholes – more rigorously. It plans to visit the spots where the trials have been conducted.
The Hindustan Times had reported how, in an internal performance report, the civic body had found only two of the total four technologies tried satisfactory.
The STAC has now demanded that the civic body should review the performance of the four technologies till February, when the next STAC meeting is scheduled, and submit a report accordingly.
NV Merani, chairman, STAC, said: “We have decided to use only mastic asphalt to resurface flyovers and bridges. STAC’s recommendations are binding on other road development bodies too. We expect the MMRDA and MSRDC too will follow.”
“We are not satisfied with the BMC giving us verbal assurances about the performance of the technologies. We want some scientific tests to be conducted to determine the properties, durability and performance,” he added.
“Mastic asphalt will be used in the upcoming repair and resurfacing work of the 34 dilapidated bridges in the city,” said a civic official from the roads department on condition of anonymity as he is not authorised to speak to the media.
“We will conduct specific tests to check technologies and will also review the performance of the technologies at each spot consistently. All this will be documented in a report that the STAC has demanded in its next meeting in February,” he added.
