The contractors, it seems, are not heeding the civic body even after specific instructions.
On Monday, as an immediate measure, the Brihanmumbai Municipal Corporation asked contractors to use Carboncor for filling up potholes, as repairs done with it will hold even under heavy rains. However, no contractor is willing to use it.
The contractors still keep filling up potholes with the conventional hot-mix, which gets washed away with rains, road engineers said.
“Using Carboncor is the only solution, as it can be used even when it’s raining,” said an official from the roads department. “Its rates are also comparative.”
The statutory technical advisory committee had also recommended the use of Carboncor. The committee had suggested that the material be considered as a solution if it does not cost more than the normal technology.
Sumer Infrastructure, the material’s supplier, has submitted the comparative rates to the BMC. The roads department said that it will consider the material only on merit.
According to a spokesperson of Sumer Infrastructure, the company had complied with the BMC’s condition.
“There is no need to attend to a patch, which has been filled up with Carboncor, for at least three years. It is clear that the comparative rates will be lower than the normal technology, as the latter needs to be used frequently,” he said.
Dr KV Krishna Rao, professor, civic engineering department of IIT, Mumbai, too had tested Carboncor and recommended its use saying it can be applied in wet weather and it doesn’t bleed in hot weather.
According to Rao’s analysis , its cost is not much higher than the traditional method.
