NCDOT uses thousands of gallons of brine on roads ahead of winter storm

The salt and water mixture was sprayed across highways as part of road pretreatment.

MAPLE, N.C. — North Carolina Department of Transportation engineers say their pretreatment solution should help ease the clearing of the roads after the winter storm passes.

“We anticipate it being an easy storm to push, even if we get 4-6 inches," said Ronnie Sawyer, division maintenance engineer. "We’re hopeful the temperatures aren’t going to be so cold where it freezes hard on the road."

Shooting 40 gallons of brine per every lane mile, DOT engineers said Thursday that the mixture is their best chance.

Engineers combined part of a 400-ton supply of salt with thousands of gallons of water, creating the tan and slushy solution.

"It’s pretty simple, it’s just a matter of getting the right mixture and salinity to the water so when it’s applied to the road it’s effective," said Reginald Saunders with NCDOT.

Saunders said 23 percent salinity is the perfect mix, and what the test for at the facility in Maple, NC. 

Sawyer said he anticipates being able to clear the highways by Friday night.
