Using FaL-G technology, roads with 300-kg strength could be laid in the rural areas under the PMGSY. “The roads need not maintenance and will last 100 years,” Director of Institute for Solid Waste Research and Ecological Balance (INSWAREB) N. Kalidas has said.

Speaking at a meeting organised by Fly Ash Brick Manufacturers’ Association here on Thursday, he said, in the rural areas, no funds were allocated for maintenance of roads once they were laid. Huge amounts were spent on roads under the PMGSY, but they went without maintenance.

“Roads laid using fly ash cost one-and-a-half times more than tar roads, but 40 per cent less than concrete roads and the strength is the same. Besides, it will create employment to 12 lakh people. The proposals have been submitted to Union Urban Development Minister M. Venkaiah Naidu,” he said.

Mr. Kalidas said 72 million tonnes of carbon dioxide emissions were reduced because of fly ash use. The number of units should be increased from 18,000 to 1 lakh, and only one per cent incentive was needed by the units, he said.

Association secretary P. Venkateswara Rao said that the MoEF notification on use of fly ash bricks in all projects, particularly those of the State government, should be implemented.

Visakhapatnam North MLA P. Vishnu Kumar Raju addressed the association members.

Association president Sureshbabu, State president K.V. Subba Rao, and MSME Director K.R.K. Prasad spoke.
