HYDERABAD: GMR Hyderabad International Airport Ltd, which operates the Rajiv Gandhi International Airport, today said it recently completed the first phase of pavement preservation of its main runway, which will extend its life for several more years.
According to a press release, GMR said the airport has used a patented Airport Grade Steel Guard (AGSG) technology, which is an asphalt protective coat application designed to preserve and extend the life of existing asphalt pavement surfaces.
This innovative technology has quick-setting feature, which enables the runway to take a load of normal air traffic after two hours of application in day-time and 45 minutes in between the layers' application, it said.
The project's first phase has taken care of almost one-third of the main runway.
During this period, the main runway was closed from 1100 hrs to 1700 hrs.
During this six-hour window, all air traffic movement was switched to the secondary runway with absolutely no impact on airport operations.
The innovative technology has helped the airport complete the project in less than 15 days as against the conventional mode of runway preservation, which would have taken more than three months to finish, the airport said.
