From a pedestrian crossing near a school to the equipment for a motorway, there are no unimportant construction sites where safe and reliable mobility for everyone is concerned


Industrial expertise and construction-work know-how at the service of safe and reliable mobility

We secure, signal and regulate the flows, acting as a comprehensive operator in safe and reliable mobility, to provide solutions to your problems, in a local and trusted relationship.

Aximum is a subsidiary of the Colas Group, a world leader in construction and maintenance of transport infrastructure.

Construction work & services

Our branches and their establishments prepare complete and appropriate solutions to private roads or motorways, fast lanes or urban highways, in rural zones as well as in the heart of metropolises. We take care to take into consideration all forms of mobility on road, rail, airport or river infrastructure.

Safe and reliable mobility in urban and rural zones

  • Securing and building traffic lanes and dedicated spaces – retention systems, equipment, road and urban marking, for example
  • Signalling to guide and inform users – vertical directional, tourist and police signage, road signage and dynamic information
  • Regulate travel and promote fluid traffic – three-colour traffic lights, variable message signs, parking management, transportation engineering

Safe and reliable mobility, permanently or temporarily

Because the safety of persons (agents, teams, local residents and customers) must be preserved under all circumstances, we have developed a set of solutions dedicated to the protection of work zones and to operation while there is a work site ongoing.

Safe and reliable mobility while improving management and maintenance

So that mobility is always safer and more reliable within the regions, we constantly seek to perfect our tools and solutions for the management and maintenance of infrastructure, thanks to permanent dialogue with your services, the know-how of our teams and our production capacity.
