the repaving was crap.... 2cm instead of the normal 7 like estoril did huge difference, who anyone who went and drove on these 2 knows the difference is huge
What sort of differences, if you could explain?
Yes, so first the tarmac is more prone to still have ´´bumps´´ because you have less of a dense and more straight level.
2- since its the ´´wear´´ part of the tarmac you will have less bitumen over time. and the first days you can see the bitumen coming off like oil... you look at estoril and the track is Dark Black all over! full of the good stuff
Here in Portimao is more ´´grey´´ meaning less of the bitumen is available in the track.
3- when you have high powered or heavier cars, the tarmac can quickly start to ´´roll under´´ meaning, under the braking zones and with these F1 cars, the tarmac is getting pushed forward over time. with just 2cm i wold say by sunday the track should already have some effects on the braking zones, so the feel of vibrations under braking coming from the track itself and not the tires little because its only a race weekend but it will some.
there is a reason the FIA recommends above 5, the minimum of the wear thread is 2 so they did the cheapest...
there is also longevity issues but when you go on a GT car as i did i can feel the difference it so i can only imagine in an F1 car.
Ps- i think they did after the new tarmac already some ´´shaving´´ of some parts. Not ideal but better than doing nothing. maybe for this year not an issue since its fresh! but if they have f1 next year, 100% they are going to have to do it all over again....
