This pavement is made up of two-layer hexagonal draining concrete slabs, prefabricated by the company Alkern at its Arthon-en-Retz (44) site, using natural local and recycled aggregates.
The slabs are laid on a bed of gravel and on a road base of porous excavable gravel.
Several functions are combined :
- The pavement can be easily and quickly dismantled and reassembled, allowing access to the underlying networks without major maintenance work,
- The handling of the slabs is optimised and facilitated by a specific tool, manufactured by the company Crealev based in Miribel (01),
- The pavement structure is porous, allowing rainwater to flow, collect and eventually be reused,
- The porous surface of the slabs is optimised for drainability, skid resistance and rolling noise.
Congratulations to the teams for this promising achievement!
