NASCAR discusses Dover track repair

Just before the halfway point of Sunday's FedEx 400 at Dover, a piece of concrete came up from the track. Jamie McMurray hit the concrete, causing front end splitter damage. The race was red flagged for more than 20 minutes while NASCAR repaired the track. Robin Pemberton, NASCAR Vice President of Competition and Racing talked to the media about it Sunday after Dover's race.
Q. Robin, a few drivers said over the radio that they saw problems with that this morning. Were any of those concerns brought to you or any of the NASCAR officials?
ROBIN PEMBERTON: We do a track walk after every race and in the morning, so at the time that had been a previous patch, but our staff, our crew didn't see anything wrong with it.
Q. I was just wondering if you could talk about the decision not to let the cars work under the red flag, especially Jamie.
ROBIN PEMBERTON: Yes. We've had issues of things like this in the past, and Martinsville comes to mind, some other things similar to that, and our policy is not to let them work on the car. You may remember when we had an equipment failure, broadcast equipment failure, sometime back, and that affected the entire field of race cars, and at that time we did red flag and we did allow the teams to fix the damage that was caused by that equipment failure. But that is our normal policy, to not allow teams to work on their cars.
Q. Can you talk a little bit about how the actual repair was made, the materials used?
ROBIN PEMBERTON: Yeah, our teams are -- we have equipment and we have product at every facility. Facilities keep it on hand. We do bring extras in case there is a need for it, but it is an epoxy type filler that we use, and it's basically the same filler that's used any time we make a repair at the track, whether it be asphalt or concrete.(NASCAR)
