Salted Roads Not as Safe as you Think

How safe are the roads treated with salt? Not as safe as you might think. Do not assume that a salted road is safe for driving. It depends on the amount of salt applied and the temperature.  We expect up to 10 inches of snow over 12 hours and temperatures down to 4F.  We can expect the application of the salt to be heavy is some places and light in others. Ice forms when the­ temperature of water reaches 32 degrees Fahrenheit. When you add salt, the freezing temperature drops: A 10% salt solution freezes at 20F. A 20% solution freezes at 2F. Typically, a salted road solution rarely exceeds 10% to 20%. Theoretically, the County could dump about 300mgs per 1kg of water to achieve a 30% solution, but that’s a lot of salt to wash into our streams and ponds.  An acre of road surface expecting 10 inches of snow would need about 10 tons of salt to achieve a 10% solution.  Don’t count on your roads having a higher than 10% salt solution. Therefore, you need to consider that patches of salted roads will freeze at temperatures below 20F (most of the next two days) and most of the roads will be problematic when the night temperatures fall to 4F. Be careful out there!  We at Junk King wish you a safe and warm 2014. saltRoads2
