Pros And Cons Of Using Salt On Street Roads During Winter

salt on icy roads

You’re probably familiar with road salt if you live in a city that gets a lot of snow and ice. Road salt is table salt in its natural state. On the other hand, table salt undergoes a lengthy purifying procedure, whereas rock salt does not. As a result, rock salt is brown or grey because it still contains impurities. 

We all know that rock salt comes with huge disadvantages for property, vehicles, and the environment. For example, can we use it as an ice melter for new concrete even though it melts ice? No, we cannot. Let us understand more about rock salt’s advantages and numerous disadvantages.

What Does Salt for Winter Do to Snow?

Salt, when applied to snow, initiates a process called salt dissolution. It works by lowering the freezing point of water, causing the snow and ice to melt at a lower temperature than they would under normal circumstances. This, in turn, helps turn the hazardous ice and snow on roads into slush, making it easier to plow and safer for vehicles to navigate.

Why Is Salt Used on Icy Roads?

The primary reason for using salt on icy roads is to improve road safety. By melting snow and ice, salt helps prevent or reduce the formation of dangerous ice patches that can lead to accidents and road closures. This makes winter travel significantly safer for motorists.

When Does Salt Not Work on Roads?

While road salt is effective in most winter conditions, it becomes less effective as temperatures drop. When the temperature falls below approximately 15°F (-9.4°C), salt’s ability to melt ice significantly decreases. In extremely cold conditions, alternative de-icing methods such as sand or ‘Traction Magic’ may be required.

Road Salt vs. Table Salt

Road salt, often referred to as rock salt, is not the same as the table salt you use in your kitchen. Road salt consists of larger crystals and is more effective at breaking up ice on road surfaces.

Table salt, in contrast, is finer and dissolves more rapidly, making it less suitable for melting ice on roads.

Advantages Of Rock Salt

The most significant advantage of salt is that it makes roadways safer. What is the mechanism behind it? The snow beneath the roads is compacted when vehicles pass over it. It then adheres to the pavement, making snow plow removal harder. 

On the other hand, road salt forms a layer of “brine” between the snow (or ice) and the road, preventing the snow from clinging to the surface. 

Disadvantages Of Rock Salt

Beyond the purchase and delivery of road salt, several other expenditures are associated with its use. For example, road salt leads to automotive corrosion and can harm buildings like bridge decking. In addition, excessive use of salt can harm the environment. 

Because salt dissolves in water, the salt concentration in groundwater rises. In addition, road salt contains sodium, altering soil pH and making it less porous.

Salt can harm the vegetation along the sides of roadways. If the salt level of the water and soil is too high, trees, shrubs, plants, and grasses can deteriorate.

The more road salt comes into contact with your vehicle, the rustier it will get. Water from precipitation comes into touch with metal car parts, releasing oxygen and carbon dioxide. In addition, road salt contains free-floating ions that come into contact with water. These ions accelerate the creation of iron oxide. The presence of salt and water accelerates the rusting process.

Traction Magic Will Erase Your Worries

Traction Magic is salt-free and entirely safe for the environment. When you use Traction Magic, it starts working right away. As a result, it avoids falls on slick surfaces around your home or business or while driving, including your driveway, sidewalk, deck, and even your roof. 

There is no safe chloride ice melter for new concrete, but this product will keep you safe from slip and fall and not damage your new concrete. In addition, it will not rust or damage any of your home’s or business components. 

It reduces on-site injuries, accidents, and lawsuits. In addition, this traction agent will keep your business safe and accessible during winter. 

Moreover, it gives your car tires quick traction on ice and snow; having Traction Magic in your automobile will provide you with stable footing during winter driving. Even though there are natural ways to melt ice, they can be ineffective and messy.



Unlike rock salt, there are no harsh chemicals or corrosive salts in Traction Magic that are known to be harmful to the environment. It acts as a fantastic soil conditioner and encourages tree and plant growth. It is free from toxic and corrosive ingredients.


A. Salt works by lowering the freezing point of water through a process called freezing point depression. When salt is spread on ice or snow, it forms a brine solution. This brine has a lower freezing point than plain water, causing the ice to melt and preventing further ice formation.

A. Commonly, rock salt or sodium chloride is used for de-icing roads. It is readily available and cost-effective, making it the preferred choice for many municipalities. Additionally, calcium chloride and magnesium chloride are used in some regions due to their effectiveness at lower temperatures.

A. The effectiveness of road salt can vary depending on several factors, including temperature, traffic volume, and precipitation. In light traffic and mild temperatures, salt can remain effective for several hours. However, in heavy traffic or during intense snowfall, salt may need to be reapplied frequently.

A. Salt becomes less effective when temperatures drop significantly below freezing. As mentioned earlier, its effectiveness diminishes notably below 15°F (-9.4°C). In such conditions, alternative de-icing methods or products like ‘Traction Magic’ may be needed to maintain road safety.

 A. ‘Traction Magic’ is primarily designed for sidewalks and walkways but can also be used on less-traveled roads.

A. ‘Traction Magic’ is effective in a wide range of temperatures, making it a reliable choice for icy conditions.
