Bouygues Group Tapped to Rehabilitate Runway 1 at Roissy-Charles de Gaulle Airport

Colas, a subsidiary of the Bouygues Group and through its subsidiaries Colas France and Tersen, has been chosen by the ADP Group for the rehabilitation of runway 1 and its 22 taxiways at Roissy-Charles de Gaulle airport (France) — in a consortium with Bouygues Energies & Services, Spie Batignolles Valérian, JDC Airports and Iris Conseil.

For the rehabilitation of this 4.8-kilometer runway and its taxiways, more than 350 employees will be mobilized over a four-month period, starting mid-July 2025. The work will include the laying of 200,000 tons of asphalt mix, 16,000 cubic meters of concrete pavement and more than 35 kilometers of airfield lighting and drainage networks.

In line with its environmental commitments and the customer’s expectations, Colas will be rolling out several innovative solutions to rehabilitate this historic runway, which opened in 1974. Among these, the use of alternative fuels, the extensive use of recycled materials in asphalt mixes and alternative structures to reduce the use of hydraulic binders, will enable  carbon emissions to be reduced by 45%, compared with initial specifications. In addition, almost 90% of demolition materials will be recycled, either directly onsite or at the group’s various recovery and recycling platforms.
