50% of the crushed aggregate road surface has been laid. Due to the weak bearing capacity of the soil, each of the 6 foundations is supported by 48 or 50 precast concrete piles with a section of 40x40cm. The precast piles have a negligible impact on the environment in which they are installed, there is no mixing of the existing soil with fresh concrete or cement slurry as in the case of piles made on site.
