Pavement strengthening: the Colgrill solution for logistics areas
In rapidly developing planning zones, the rise of logistics platforms is significantly transforming infrastructure usage. Increased heavy goods traffic places considerable strain on existing structures and accelerates their aging. Cracking, deformation, and loss of load-bearing capacity occur more quickly, compromising road durability.
In response to these challenges, pavement strengthening offers a high-performance alternative to full reconstruction. In a rapidly expanding development zone (ZAC), Colas teams in Tours implemented the Colgrill solution to sustainably adapt the main access road to increased traffic volumes.
Strengthening rather than rebuilding
In a logistics context, fully reconstructing a pavement results in high costs, significant downtime, and substantial material consumption. Strengthening, on the other hand, makes it possible to preserve the existing structure while improving its load-bearing capacity.
This approach optimizes investment over the infrastructure’s lifecycle and reduces the environmental impact of the project. It therefore meets the growing demands of developers and operators in terms of performance and sustainability.
Colgrill, a proven structural reinforcement solution
Colgrill combines a high-performance reinforced asphalt layer with a heat-bonded fiberglass grid. This system helps limit crack propagation and improves resistance to fatigue under repeated heavy goods traffic.
Beyond the process itself, the added value lies in the design method developed by Colas. Drawing on more than 30 years of experience, the company precisely models the behavior of reinforced structures to optimize their long-term performance. Each project is therefore tailored to the specific constraints of the site.
Mesurable benefits for logistics stakeholders
Pavement strengthening with Colgrill makes it possible to:
- increase the lifespan of the structure
- reduce maintenance operations
- optimize asphalt layer thickness
- decrease the volume of materials produced and transported
- lower the project's carbon footprint
- ensure a 100% recyclable process, under the same conditions as conventional asphalt
For operators, this results in better control of maintenance costs, reduced operational downtime, and infrastructure capable of supporting evolving logistics flows.
A solution that can be integrated into a comprehensuve development approach
Colgrill can be combined with other technical solutions developed by Colas to provide a comprehensive response to the specific constraints of each project. The process is suitable for industrial areas, logistics platforms, urban roads subject to heavy traffic, as well as access routes dedicated to heavy goods vehicles.
As a global developer of regional infrastructure, Colas supports both public and private stakeholders in sustainably adapting their infrastructure by integrating structural performance, environmental control, and a long-term vision.
The evolution of logistics uses requires infrastructure capable of handling increasing loads while controlling environmental impact. Pavement strengthening using the Colgrill process aligns with this approach to sustainable adaptation, combining structural performance with environmental responsibility.
