LACONIA — Public Works trucks have begun applying a brine solution to roads even though the snow season has not yet arrived.
Department Director Wes Anderson said asphalt is porous and it is effective to get salt in the roadway before the snows come. It also helps prevent black ice from forming when moisture hits the road in freezing temperatures.
“We are on day three of applying the brine solution today, and everything is working well,” Anderson said Thursday. “But we have been getting some calls from people and questions about what is being applied. We are using rock salt, mixed up in a 23 percent solution.”
Motorists are advised to stay well back.
“You don't want to be within the spray area, but it's not any more corrosive than the salt we put down during the winter,” Anderson said.
The liquid helps the salt spread uniformly and stick to the surface. The water evaporates and this leaves a thin film of salt that will help prevent ice from forming.
The heavy snow period differs from year to year, but often begins around Christmas and extends to March.
Sand is seldom used on local roads as it tends to reduce traction once the road is dry, Anderson said.
The best bet for reducing corrosion on vehicles is to go to the car wash for an underbody spray when roads return to dry pavement after a snow storm.
