Having had no notification in pre-event notes from the FIA relating to any resurfacing, the color of the asphalt – which has already worn away on the racing line in locations – left some concluding that the circuit had had a paintbrush taken to it.
As Daniel Ricciardo stated: “It seems to be like they’ve painted the monitor or one thing. They’ve completed one thing to the floor.
“I do not understand how the monitor’s going to alter, or if it may be the identical or tremendous slippery. However perhaps that adjustments the best way the tyres behave.”
Ricciardo was not the one driver questioning what the influence can be on a weekend when groups are aware that there’s only one hour of follow earlier than dash qualifying begins.
World champion Max Verstappen stated he hadn’t seen something prefer it since his karting days when efforts have been made to enhance grip on outdated tracks.
“It seems to be like they’ve painted it, not resurfaced,” stated the Purple Bull driver.
Ferrari’s Carlos Sainz defined that the scenario had left drivers and workforce a bit confused.
“I believe there are lots of unknowns, particularly the tarmac seems to be prefer it’s been handled in a really explicit manner,” he stated.
“I do not suppose the FIA or the groups fairly perceive what has been completed right here: if it has been a full resurface or only a bizarre bitumen therapy to the monitor.

“It definitely seems to be very explicit, and one thing we’ve not discovered just lately at F1 circuits.”
However analysis by Motorsport.com has uncovered that whereas the monitor seems to be prefer it has been painted, what has occurred is definitely a bitumen floor therapy that’s generally used on roads in the USA and Asia.
Bitumen is utilized in fluid kind to the monitor floor to assist bind with the floor of the prevailing circuit. The concept is that it helps get rid of mud, improves waterproofing and likewise stop disintegration of the monitor.
It’s understood that this work was completed in Shanghai final 12 months, and the numerous colouring across the monitor is the results of this therapy having been worn away from monitor working that has taken place since.
The way of the therapy means it is going to seemingly additional be worn away over the F1 weekend, which may open the door to diversified ranges of grip round totally different components of the monitor.
Haas workforce principal Ayao Komatsu stated variations in grip triggered by the therapy being current or not may ship some complications.
“I believe it seems to be a bit inconsistent,” he stated. “That inconsistency is what I fear about essentially the most – the inconsistency from entry to mid-corner to exit in every nook. If it is variable, that is going to be fairly difficult.
“Then, in fact, it is a dash weekend. You could have solely received one hour, in all probability three runs to kind your automobile, each high and low gas. I believe it may be a really powerful problem.”
No Turkey repeat
The looks of the darkish floor layer has inevitably triggered recollections of Turkey 2020, when groups and drivers have been caught out by a exceptional lack of grip on a newly layered floor.
However Sainz was fairly assured issues weren’t going to be that dramatic – as sources recommended the therapy ought to really assist enhance grip moderately than scale back it.
“I’ve the sensation it isn’t going to be like Turkey,” he stated. “Turkey was a really explicit case. But when instantly there’s graining and all that, that would throw some query marks in your selections for the remainder of the weekend.”

However whereas the monitor therapy could not set off the type of chaos we noticed in Turkey, it may definitely have an effect on how the tyres carry out.
Groups aren’t certain but if the present automobiles and tyres are going to lean in direction of a weekend the place entrance graining is the restrict, or if the best pressures of the 12 months to date will set off big degradation points.
A weekend of graining, like in Australia, could possibly be excellent news for Ferrari – whereas degradation would higher swimsuit Purple Bull.
As Sainz stated: “I believe, truthfully, for us, graining could be very tarmac dependent. That’s the reason we have been speaking a lot in regards to the floor, what they’ve completed with the therapy of the tarmac, as a result of graining could be very tarmac-dependent.
“As soon as you are taking that out of the equation, the long-duration corners are one thing that stresses the tyre massively and right here, we’ve got loads of these.
“There have been years the place China has been front-limited, years the place China has been rear-limited, so adapting the automobile to whichever demand, you need to be very cautious when establishing the automobile.”
