In order to broaden its range of road engineering skills and provide a comprehensive response to its customers' requirements, Groupe Géotec has developed a business focused on roads and their infrastructures.
With more than 1 million km of roads and nearly 250,000 bridges in France, road and infrastructure maintenance is undoubtedly a major challenge for the years to come. In this context, Groupe Geotec aims to become a key player in this field, providing solutions for the entire value chain:
- Network testing.
- Analysis of causes of deterioration and implementation of indicators.
- Interview scenarios.
- Maintenance program and job sizing.
- Control of completed work.
ROAD BUSINESS MISSIONS
Project ownership and project management assistance
The department is responsible for all motorway project management tasks, assisting project owners with their road and other infrastructure development projects.
Pavement diagnostics
Road diagnostics enable maintenance work to be prioritized and prioritized, as well as a detailed approach to the associated budget envelopes, whether for concrete or asphalt pavements.
Exterior pavement inspections
In the field, external inspection campaigns are jointly defined and planned with the project owners. On-site investigations and laboratory tests validate the acceptance of subgrades, aggregates, bitumens, asphalt mix manufacture and application, skid resistance and road markings.
Road engineering
Road engineering on existing pavements completes the road diagnosis by optimizing the technical proposals. A complementary campaign consisting of various in-situ investigations can be proposed. The data collected can be used to delimit any disorders and precisely define the homogeneity or heterogeneity of structures. Finally, resizing confirms the reinforcements to be planned. Road engineering on new roads enables structures to be optimized according to site configurations.
L'ingénierie routière sur voiries neuves permet d'optimiser les structures suivant les configurations du site.
Road engineering on new pavements enables structures to be optimized according to site configurations and geotechnical data.
Pavement surveys
Teams respond immediately to customer problems arising from technical or geological incidents.
