Mario Isola, head of the F1-department of Pirelli, expected in the pre-season test in Barcelona that the job bright will evolve as the test days are progressing. Last week received the ‘Circuit de Barcelona-Catalunya ” after all, a new tarmac-layer.
The circuit agreed to a number of adjustments to ensure that they are also in 2018 will still be on the MotoGP calendar. Earlier this month, was started the work to get the job of a new layer of asphalt and also the uitloopstrook to turn thirteen is a lot bigger.
Pirelli wants to have homework ready at the first F1 test that will take place on 26 February and will be next week and already some of the engineers into Spain to send all the new tarmac-layer to examine.
“There is told me that the goal was to have the new asphalt in terms of roughness, just the same as the old,” said Isola against ‘Autosport’. “It is clear that the new layer is never identical to the old one, but that was the goal.”
“Usually we test the Wednesday before the training how rough the track is. The plan is to next week engineers to there to send the new layer with the old to compare.”
“I know that in the time between the end of the work and the beginning of the F1-test as many cars as possible on the circuit want to drive in an attempt to get it to stabilize. In the beginning, evolves, of course, at a high tempo because you have to deal with oil, tar and a number of other issues.”
After a few days will the new tarmac-layer are not so quickly to evolve, and they will have to deal with more stable conditions to test, ” says Isola. Pirelli need the compounds for the GP of Spain yet to be revealed and the Italian thinks that the new asphalt their choice more difficult.
“The problem is that we need to consider to make other choices because we choose our compounds on the basis of the roughness and the layout of the track and the energy that passes through.”
“We have a database and on the basis of that information, we will take a decision about which compounds we will use.”
“It goes without saying that if you make a change such as in Sepang in 2016, when they have a new tarmac-layer put with a totally different composition, that is a very different choice than in the past. Sepang was one of the most aggressive circuits in and after the renovation we had the opportunity to take a step softer to go.”
“Last year in October we had in Jerez the same case. In that month there was a new tarmac-layer laid and there was a race weekend, with the F2 and GP3 in the program. We also sent for the race engineers to there to the roughness of the track to measure and it was totally changed, it was much smoother.”
“We have chosen to go one step softer to go in our compounds but that was not enough. Asphalt can make a world of difference,” concludes Isola.
