Salt loses effectiveness on roads in bitter cold temperatures

When temperatures dip below freezing, the Fayetteville DPW starts enhancing it's salt so it works better.
Fayetteville (WSYR-TV) --When temperatures dip below freezing, the Fayetteville DPW starts enhancing its salt so it works better.

“When the temperatures go as low as they did today, we use the other additive - which we call hot mix – which takes the road down, burns off the snow and gets it back to where people can travel,” explained Patrick Massett with the Fayetteville DPW.

That additive helps activate the salt so it can melt the snow. Fayetteville also sprays a liquid on the roads the night before a storm to help speed up the process and keep roads clear.

In Syracuse they use strictly salt, which usually works just fine, but when it gets this cold out salt loses it's effectiveness. And when temperatures dip below zero, it hardly works at all.

“It slows things down. The process isn't as quick, so instead of five minutes after application it may be 15 minutes. With the sun popping out today that's Mother Nature helping,” said Tom Simone with the Syracuse DPW.

And even if the salt doesn’t work very well, the DPW still puts it out on the roads to create some traction for cars.
