100 million euros sounds WAY over the top, to me.
We put a mega over-slab on top of our main runway at LGW a few years ago to cure some reflective cracking problems from the old concrete runway built in the 1950s. That came in at under £20million and included a complete replacement of all the CATIII lighting as well.
As you know, we're the busiest single-runway airport in the world with many 777 rotations a day, as well as A330, 747, DC10 767 and other heavies. We keep on top of the maintenance of course with frequent night closures and Northern runway ops but we're vey pleased with the way the main runway is standing up to the pressure.
The main problem we found after all the work was everyone complaining about the lights being too bright, even on 3% setting, as they finally now meet the spec!
Perhaps ORY have some hidden agenda and are using this as an excuse???
Cheers,
