Aggregate Industries is conducting a full review of its work on Silverstone’s racetrack after standing water forced the cancellation of the British MotoGP Grand Prix last weekend.

Race organsiser Dorna was forced to cancel the race for the first time since 1980 after the start was delayed by six hours as repeated efforts were made to clear standing water. It will have to refund 56,000 ticket holders.

Aggregate Industries has come under fire as the contractor that carried out a full resurfacing of the circuit earlier this year.

Immediately after the race was called off, circuit owner Silverstone said it would be looking at whether Aggregate Industries’ work was the cause of the standing water problem.

“All the work we have done here to make Silverstone a better place for motorcycle racing has been done with the best of intentions. We will be making further investigations into this matter immediately after the Bank Holiday to understand whether our newly resurfaced track played a part in today’s inability to stage races,” said Silverstone managing director Stuart Pringle.

“We will be reviewing all the data we have on the track and gathering more, and together with the contractor, Aggregate Industries, a full investigation will be carried out,” he added.

Aggregate Industries told New Civil Engineer that it was working in “close partnership” with Silverstone, conducting a “full review” of the track resurfacing over the next few days to better understand the issues caused by the extremely wet conditions on raceday.

It said that it would continue to make resources available to assist its client during this “difficult period” and added that once concluded, it hoped to share the findings of the investigation.

This year was the first time since 1996 that the track at Silverstone, home to the Formula 1 British Grand Prix, was fully resurfaced.

The work was intended improve racing by ironing out bumps and uneven surfaces and removing differently-aged asphalt sections that had different performance characteristics.

It was completed in four weeks.

Some 40mm to 60mm of basecourse was removed and replaced, depending on the racing line and other factors such as the camber of the track. Investigations are now focusing on whether the profiling was carried out correctly.

“The best circuit in the world is shortly to get even better,” boasted Pringle at the time. “I’m hugely excited about the enhanced and, importantly for motorcycles, consistent grip that the new Aggregate Industries’ asphalt will provide. We’ve updated sections of the track over the years but a full resurface has not been undertaken for decades. I am quite sure we’ll see lap records tumble this year not to mention witness even closer, dramatic racing.”

He added: “It’s hugely impressive to see the accuracy that the Aggregate Industries team is working to. We are addressing some known bumps and dips as well as improving drainage. The result should be very close to the perfect surface for a racing circuit.”
