How does mag chloride work?
Magnesium Chloride: Magnesium Chloride is a hygroscopic, deliquescent compound that attracts moisture from the air and resists evaporation. Magnesium binds fine dust particles to keep roads stabilized, to slow the loss of aggregate, and to reduce the need for costly regrading.
Do cars rust in Colorado?
Cars are famously rust-free from Colorado, despite all the snow — and that’s because, in spite of Denver’s 54 inches of annual snow, the average January high is 45 degrees — enough to melt all but the biggest snowfalls and enough to ensure they don’t have to dump too much salt on the roads.
What does magnesium chloride do to your car?
Unlike sand/salt mixtures, the liquids will not damage your car’s paint job or windshield.” Now, mag chloride seems fairly innocent in the aforementioned statement. After all, it won’t damage your vehicle’s paint or windshield.“Magnesium Chloride is especially corrosive to metals, and therefore vehicles.”

Why are roads red in Colorado?
“The aggregate used in the chip seal looks to have a high concentration of scoria rock in it which gives it the red color. Crews then came back in and milled the centerline for the rumble strips. Once the rumble strips are milled, they’ll go over the top with a sealer. That’s the dark black.
Which states use salt on the roads?
Twelve states, Colorado, Connecticut, Illinois, Indiana, Maine, Massachusetts, Montana, New Hampshire, New Jersey, Pennsylvania, Rhode Island, and Virginia, use a salt and sand mixture with a rate that typically falls within a range of 250 to 300 pounds per lane mile during snow and ice conditions.
At what temp do roads freeze?
32 degrees Fahrenheit
When Do Roads Ice Over? The freezing point of water is 32 degrees Fahrenheit.
Does Colorado use salt on its roads?
The Colorado Department of Transportation has begun using a salt brine mixture on roads before snowstorms to aid the melting process.It is useful but has hidden risks that soar into the millions of dollars in devaluation of vehicles and road infrastructures. Salt causes rust on all exposed steel parts of vehicles.
How do I winterize my car in Colorado?

What is the liquid sprayed on roads for ice?
Brine
Brine is a mixture of salt and water and it’s used in place of salt crystals on roads because it stays in place better. When rock salt crystals are spread on a road, a large percentage of them bounce and roll off to the side where they are of no help keeping the road free of ice and snow.
What do they use on icy roads?
Using road salt is a means of freezing point depression, which means that road salt can lower the freezing temperature of the water. When temperatures are below 32 degrees Fahrenheit, sprinkling salt directly on icy roads can melt icy patches on the roadway.
What is the difference between magnesium chloride and Calcium Chloride?
The difference between calcium chloride and magnesium chloride is that the calcium chloride contains a calcium cation with two chloride anions whereas the magnesium chloride contains a magnesium cation with two chloride anions.
Which is better for dust control Calcium Chloride or magnesium chloride?
If relative humidity is high, the solution volume grows. If conditions are dry, the opposite occurs. Calcium chloride remains liquid in hot, dry weather, extending dust control under conditions when magnesium chloride solidifies and provides little if any dust protection.
