Slippery track surface in Austin due to ‘sweating’ oil 18 November, 2012 Fernando Alonso Ferrari Nov.18 (GMM) The particularly slippery conditions experienced by drivers at the new Circuit of the Americas this weekend is caused by oil, not dust. That is the claim of the authoritative German publication Auto Motor und Sport, which said Texas’ colder-than-expected temperatures and too-hard Pirelli tyres are also contributing to the problem. But the biggest factor: “The brand new asphalt is sweating oil,” said the report. “[Circuit designer] Hermann Tilke told Charlie Whiting that it is the same type of asphalt as in India and Korea,” added journalist Michael Schmidt. Pedro de la Rosa does not agree: “The asphalt here is different,” said the HRT driver. Fernando Alonso claims that the Austin track – “is very smooth and not at all porous” – and that it reminds him of Portimao in Portugal. Schmidt said that the Spaniard is right. Pedro De la Rosa confirmed: “You can see the oil shimmering when you look at the track in the morning.” Subbed by AJN.
