Aggregate Industries, which conducted this year's resurfacing of the Silverstone circuit, will be 'conducting a full review' following the cancellation of Sunday's British ꧙MotoGP.

Riders were disappointed to find the new surface seemed at least as bumpy as the former asphalt when they took to the track on Friday. B🧸ut the critical issue in terms of the race would be the amount of standing water that accumulated on the asphalt after rain.

A spokesperson at Aggregate Industries told ltxcn.top: "We are working in close partnership with Silverstone and will be conducting a full review of the track resurfacing over the next few days to better understand the issues caused by the ext🉐remel𒅌y wet conditions on Sunday. We will continue to make resources available to assist our client during this difficult period."

A brief but heavy s🎃hower on Saturday afternoon caused a spate of aquaplaning incidents at the end of the 200mph Hangar Straight, resulting in a broken leg for Tito Rabat when he was hit 🦩by Franco Morbidelli's fallen bike. The race start was then moved to try and avoid the worst of the forecast Sunday weather, alongside overnight drainage work at the Stowe/Club sections.

But, after a dry warm-up, the rain arrived and the early 11:30am start was delayed after riders again st෴ruggled with aquaplaning on their way to the grid.

Rain continued at a mostly moderate level throughout the day and, despite efforts to sweep water from the track, at a 4pm riders' meeting those present (168澳洲幸运5官方开奖结果历史:controve𓄧rsially, not all of the riders) voted overwhelmingly that it would be unsa🍒fe to race.

It was the first time since 1980 that an event has been cancelled completely. The option of a Monday race was rejected by so♑me teams due to logistical reasons, with a private test at Aragon starting on Wednesday.

Silverstone previously hosted torrentially wet MotoGP races in 2011 and 2015, prompting Race Director Mike Webb to conclude this year's problems were "a direct result of the [new] ♓track surface."

“We’ve had a number of years of experience here in very wet conditions and with the old surface we have been able to run races," he c🐼onfirmed. "This year with the new surface is the first time we’ve had quite so much standing water in critical places on the track.

“It depends entirely on the rain, how consistent and how long it is. In Moto2 practice when it was raining it was a normal session. But when the water does not drain away from the surface it builds up, so if you have had relatively light rain for a long time you get suꦇrface water.

“For the first two hours it is fine, bu✤t then [the surface water] getsꦗ worse and worse. It is a unique situation and we’ve never had to cancel a race like this.”

On Sunday evening, Silverstone Managing Director Stuart Pringle said: "I know that the contractor, Aggregate Industries, did this [resurfacing] because they are proud of their workmanship and proud of the quality of their prod🎉uct.

“It would be unfair to round on them now when we don’t have data. We need more data… We will of course be scanning [the track surface] a🅘gain and getting some independent eyes on this as well. We need to get to the bottom of this.

“This is a serious matter for the MotoGP championshi🅰p and this is a serious matter for Silverstone. We need🃏 to present answers and understand what's gone on, and what's needed for the future."

While the top priority wil🥀l be to fix the drainage🅘 issue, the bumps are also sure to be investigated.

FIM safety officer Franco Uncini felt 'something changed' from his first inspection of the new 𓂃asphalt, when only two areas of the track needed corrective smoothing, after which it was descr🎀ibed as 'perfect'.

“I came after they laid down the new asphalt at the end of February. At the time I did the inspection and tꦉhe tarmac looked very good, a small matter of [fixing a few] bumps. A factor that was confirmed by Cal Crutchlow 🍃who did a test on a bike one month later. He confirmed two places that I said were a little bumpy.

“The circuit reacted and adjusted 🌌these two bumps and they said it was really perfect at the time. But slowly we discovered💙 during Formula 1’s Grand Prix that it was bumpy.

🌳“It was from March to July that was the situation of the tarmac [changed] – I don’t know what happened. They will do a deep study in the next six weeks to see what is the reason because in February and March it was good. This is the first time any asphalt did this in the past 20 seasons. It has never happened before.”

Aquaplaning

Aquaplaning is when excessive surface water causes tyres 🐬;to lose contact with the track, meaning riders can no longer control their machines.

Suzuki's Alex Rins, who was seen desperately trying to warn other ri📖ders after bailing off at Stowe cor🃏ner on Saturday, said:

"When I arrived I saw a lot of water and I cut the throttle in the midd𒐪le of the [Hangar] straight but when I braked, the front tyre was locking fully. That means a🍒quaplaning. But this was at 210-220 km/h so there was no time to reduce the speed and I decided to jump off the bike. Then I did all I could to warn other riders.

"Morbidelli crashed because of the aquaplaning and then his bike hit Rabat [in the grave📖l trap] and made him fly 3 metres. So it was bad."

'We can’t schedule a test hoping it’s going to rain'

While bumps can be easily ide꧅ntified during a test of the circuit with a high-performance road bike, surface drainage and aquꩲaplaning cannot.

"The specific problem here is standing water after either continu🙈ous rain, or the very heavy short burst of rain tha𒊎t we had on Saturday," Webb reiterated. "Yes, we would love to have a test in those conditions before we race here but we need to find a way how. The problem is to actually technically replicate those conditions. We can’t schedule a test hoping it’s going to rain.

"After our experience in Qatar with the [artificial] wet test th🀅ere, it’s an enormous exercise to wet a track sufficiently to get real data."

Uncini added: "There is no system&nbs💦p;to check the track in the wet. We check the track in the dry and we presume that in the wet it should be okay, with the correct drainage on the sides and the inclination of the track everywhere. So we only trust the company that makes the asphalt and we trust the circuit.

"We just check that is not bumpy, that it has good grip, that is not slippery, that there is no gap in-between the kerbs and the asphalt... We check all these🐟 particulars, but we cannot check in the wet because, for example, how wet is it? Ho🧔w would we consider that could be okay or not? Which is the system to check?

"The only system should be with a MotoGP bike on a completely wet track. Quite impossible [to test in adv🔯ance]."

The benefit of hindsight

With hindsight, the only chance for a race on Sunday would have been before the two-hour rain 'limit' had been reachedᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚ, after which the surface became waterlogged and aquaplaning occurred.

Rain began straight after MotoGP warm-up at 9:20am, meaning - des🗹pite the wise effort to change the race day schedule - the track was already soaked by the new 11:30am start time.

But with most forecasts suggesting 🍌;rain from 9-10am on Sunday, could the start time not have been moved ev🌳en earlier, scrapping warm-up if necessary?

"Looking at the we꧑ather forecast, the idea was the earlier the better," Webb confirmed. "We discussed about earlier starts, but the teams and more specifically the organisers need a certain amount of time to get people into the circuit in the morning and that is also a consideration. We need to consider thꦿe promoter's needs as well. The compromise and the times agreed were after consolation with all teams and the promoters."

The original race start time was 1pm.
