NASCAR uses specialty track-drying technology to rid the rain from racetracks

There has been a 50 percent decrease in drying time because of the technology.

The weather has often been the biggest challenge for auto racing, but the impact of rain is now significantly reduced thanks to track-drying technology.

NASCAR's Air Titan 2.0 is a track-drying apparatus that uses compressed air to push water off the racetrack.

On oval tracks, like the Daytona International Speedway, races cannot happen if the course is wet. Slicks, the tires used at oval tracks, cannot handle the precipitation due to the lack of tread pattern on the tires.

Thomas Davenport, Manager of Track Services for NASCAR, says that the Air Titan trucks use a large volume of air to rid the excess moisture off the speedway.

"The air from the blower goes through a series of hoses, and it comes down on an air knife that you see pulled along behind the truck," Davenport says. "In a sense, it's a squeegee, but it's of air. So, if you think of folks squeegeeing water off a window or things like that, it's the same effect. We just use it with air."

But the work isn't done yet. Once the trucks have done a couple of laps around the track, it is then up to air blowers to rid the moisture from the pores on the tracks.

"We use our buffalo turbine air blowers, and we use our jet dryers to combine and apply heat to the surface, just like you would think of a hairdryer," Davenport explains. "You know when you're drying your hair out, right, you use the towel and ring your hair out to get the excess moisture off and then the hairdryer is just getting what's left behind. It's the same way with the jet dryers. Jet driers come behind and take out the rest of that moisture that's in the top layer of the asphalt."

There has been a 50 percent decrease in drying time because of the technology.

And Davenport says that there's an efficiency standpoint that makes a big difference.

"When you can cut down the drying time and the run time, you're your efficiency across the board goes up," he says. 

While the forecast looks mostly dry, Davenport says that all 20 Air Titan trucks, plus the two service trucks that support the fleet, will be ready in case the track needs drying.
