Road signage and markings
A major player in safety, signage, and traffic optimization, our subsidiary Aximum designs, manufactures, and implements comprehensive road signage and marking solutions. From diagnostics to maintenance, the teams ensure safe travel on roads, highways, and urban areas, while addressing performance, innovation, and sustainability challenges.
Engineering, manufacturing, construction & services
Studies & design
Our design offices carry out road network diagnostics, develop signage plans and traffic schemes, and program traffic lights and dynamic devices.
Each project complies with national and European regulations (NF, CE) and relies on traffic simulation and modeling tools.
Manufacturing & products
Aximum operates industrial sites specialized in producing paints, resins, thermoplastics, and signage panels.
Our certified ranges ensure adhesion, durability, and visibility, day and night, in all weather conditions.
Our commitments for safer and more
sustainable mobility
Our expertise in signage
Horizontal signage (road markings)
A specialist in road markings, Aximum designs and applies solutions adapted to all environments: urban areas, parking zones, interurban roads, and highways.
Our cold paints, two-component resins, and thermoplastic products ensure optimal visibility and long-lasting adhesion, regardless of weather conditions. We also carry out specific markings for bike lanes, airports, industrial sites, and parking facilities, contributing to safer and clearer mobility across the entire network.
Vertical signage & wayfinding
Aximum manufacture, install, and maintain all regulatory, directional, and dynamic signage equipment. Our panels and gantries, compliant with NF/CE standards, ensure mechanical strength, durability, and long-lasting legibility.
We also support local authorities and infrastructure managers in implementing bicycle wayfinding and variable message signs (VMS) for smoother, safer, and smarter traffic management.
Construction site safety & signage
Light and heavy signage
Aximum Deploys temporary traffic control devices to secure road and highway construction sites, including cones, separators, concrete blocks, and warning lights.
Our teams manage the installation, monitoring, and removal of these devices, fully complying with safety regulations.
Safety barriers & crash attenuators
To protect road users and construction personnel, we design and install metal guardrails, impact attenuators, and CE-certified modular barriers. These devices help control vehicle trajectories and reduce the severity of accidents.
About Aximum
Aximum, a subsidiary of the Colas Group, designs, manufactures, installs, and maintains traffic signage, safety, and management equipment. As a leading player in safe and sustainable mobility, Aximum supports local authorities and infrastructure managers from engineering to maintenance, providing reliable, compliant, and high-performance solutions.
Traffic management & connected solutions
Traffic lights and luminous devices
Aximum designs and maintains intelligent traffic light intersections with detection, supervision, and remote control. These systems prioritize public transport, ensure the safety of active mobility modes, and improve urban traffic flow.
For temporary operations, we deploy autonomous mobile traffic lights, illuminated panels, and connected devices that can be managed via our IoT platforms.
Data and industrial expertise
Our teams collect and analyze traffic data (counts, FCD, inspections) to help local authorities plan mobility and maintain their equipment.
Aximum also leverages its industrial know-how for the formulation of paints and bitumens and the production of electronic boards, supporting increasingly reliable connected solutions.
Innovation & sustainability
Flowell, the interactive luminous road marking
Developed through our R&D, Flowell is an integrated luminous road marking technology.
This innovation enhances nighttime visibility, improves pedestrian crossing safety, and demonstrates our commitment to smarter and safer mobility.
Research, eco-design & maintenance
Aximum’s R&D supports our design offices and laboratories to develop solutions that are both high-performing and sustainable.
Our equipment is made from recycled or bio-based materials and designed to minimize environmental impact throughout its lifecycle. Among these innovations, Axiroof exemplifies this approach: a water-based, low-VOC paint that lowers urban surface temperatures and helps mitigate heat islands.
With teams across the country, we handle the installation, renovation, and maintenance of signage devices, ensuring continuous quality monitoring.
Frequently questions
Horizontal signage refers to road markings on the pavement (white lines, symbols, zebra crossings, colored zones), while vertical signage includes panels, gantries, and luminous devices. Both types of signage work together to ensure clear guidance and safe travel.
Depending on the type of surface and traffic level, Aximum uses cold-applied paints, two-component resins, or thermoplastics. These materials ensure excellent adhesion, high visibility both day and night, and durability suited to the intended use (urban roads, highways, airports, etc.).
The products and processes developed by Aximum are designed to minimize environmental impact: low-solvent formulations, recycled or bio-based materials, and optimized durability and recyclability of the supports. This approach aligns with the Colas Group’s commitment to more sustainable mobility.
No. In addition to roads and highways, Aximum operates in a variety of environments: urban areas, parking lots, bike lanes, airports, race tracks, and industrial sites. The company designs and maintains signage equipment for all types of circulation spaces, regardless of their use.
