London Gatwick Airport has resurfaced its main runway in half the time and at half the cost of traditional resurfacing methods.

The VINCI Airports/VINCI Concessions operated hub laid 40,000 tonnes of asphalt, 100,000 tonnes than would normally be used to resurface the airport’s main runway. Using just 30% of the usual amount of asphalt meant a considerable reduction in embodied carbon, the operator said.

All of the old asphalt materials were recycled for use as aggregates in road construction, while a temporary on-site asphalt plant reduced the distance travelled by lorries and the associated emissions.
