Colas wins the contract to rehabilitate runway 1 at Roissy-Charles de Gaulle airport

For the rehabilitation of this 4,8-kilometer track and its access roads, more than 350 employees will be mobilized for 4 months, starting in mid-July 2025.

The work will include the installation of 200.000 tonnes of asphalt, 16.000 m3 of concrete pavement and more than 35 kilometres of aeronautical lighting and sanitation networks.

In line with its environmental commitments and customer expectations, Colas will deploy several innovative solutions to rehabilitate this historic runway, opened in 1974. These include the use of alternative fuels, the significant integration of recycled materials in the asphalt mixes, and alternative structures to reduce the use of hydraulic binders, which will reduce carbon emissions by 45% compared to the initial specifications. In addition, nearly 90% of the materials from the demolition will be recycled, either directly on the operation or on the Group's various Valormat recovery and recycling platforms.

For Thierry Méline, President of Colas France: "The Colas France teams are proud and grateful for Groupe ADP's renewed confidence in carrying out this project. This project illustrates our ability to combine technical performance with environmental commitment, and contributes to the modernization of airport infrastructure for a more efficient and sustainable runway."

This new contract demonstrates Colas' expertise in building or modernizing airport infrastructure. Several renovations have been completed in recent years: runways 3 at Orly and Roissy-Charles de Gaulle airports, and those at Nice Côte d'Azur and Luxembourg airports. Colas also recently delivered the third runway at Bangkok International Airport and is currently building a taxiway at Los Angeles International Airport.
