TDOT uses new technology for pothole repairs

Posted: Updated: March 26, 2013 10:45 AM

With pothole season in full swing, the Tennessee Department of Transportation is working to stay on top of potential traffic nightmares with new technology.

While construction to repair potholes slows traffic down, TDOT's goal is to prevent future problems for drivers, including wrecks, flat tires and alignment issues.

Interstate 440 is the biggest problem area since the road is concrete, not pavement.

TDOT crews told Nashville's News 2 concrete is harder to patch because the mix doesn't bond to concrete as well as pavement.

Since July, TDOT has spent more than $265,000 repairing potholes in Davidson County.

This year, they're using a new machine called an infrared pavement recycling machine, which heats the affected area, spreading the asphalt out smoother, allowing it to last longer.

Crews patch approximately 40 potholes per day on Tennessee Interstates.
