Special pavement used by Alabama DOT to help prevent hydroplaning

Drivers always need to be cautious on the road during wet or icy conditions; however, open grade friction course asphalt, a tool used by the Alabama Department of Transportation, is making some roadways in Huntsville safer.

“Basically the way it works is due to the size and make up of the aggregate, it’s more porous so open graded friction course is water permeable and it allows water to pass through it and drain off better than your typical road surface,” said Alabama Department of Transportation’s Public Information Officer, Seth Burkett.

This special asphalt gives your tires better traction regardless of the weather conditions. ALDOT started using this kind of asphalt on highways and interstates to help lower the chance of hydroplaning.
