The quality of roads in the city will improve if the civic body implements the suggestions of the state-appointed Standing Technical Advisory Committee (STAC).
The state government-appointed advisory committee, in their meeting on Thursday, recommended a new technology called geo textile to increase the durability of bituminous roads.
According to the committee, the technique promises to increase the durability of roads by 20 years.
This geo textiles, mainly made of jute, are placed in layers between the surface of the bituminous roads and the sub-base layers. These textiles help in faster dissipation of pore pressure and better drainage, resulting in better roads.
Mostly the shelf life of bituminous roads is between 10 and 18 years and these roads are more prone to cave-ins and
The technique has been used by municipal corporations of Pune and Nashik and has known to adapt the Indian roads condition very well.
Members said the technique also helps in reducing the uneven stretches that develop on the bituminous roads.
NV Merani, chairman of STAC committee, said the BMC has been advised to undertake a pilot project by using this technique so it would have to spend less money on concretisation and to improve quality of the asphalt roads.
The city has a network of 1,900 km of roads of which 500 km is concrete while the majority is made of asphalt.
“The designs for these will be provided by the Indian Institute of Technology (IIT) and the Indian Road Congress (IRC),” said Merani.
Additional municipal commissioner Aseem Gupta said the BMC was open to trying new technologies that will help better the quality of roads.
“If the IRC and the IIT are guiding us, then we can take up a pilot project to try the technology,” said Gupta.
The STAC said the BMC should undertake inspections of the city’s bridges twice a year, before and after monsoon.
