sand vs salt for deicing roads

Deicing is a significant task in avoiding accidents during winter. The two most commonly used materials for this task are sand and salt. Each material has benefits and drawbacks, and the best decision depends on various factors.

Benefits of deicing with salt

Salt is considered one of the most traditional substances used for deicing, and it is an efficient way to melt the ice on the road surface. When salt is applied to the ice, it dissolves and creates a saltwater solution. This solution lowers the freezing point of water, allowing it to melt the ice. However, excessive use of salt can be detrimental to the environment, as it can cause corrosion of metal and can also lead to soil and water pollution.

Benefits of deicing with sand

On the other hand, and is also a popular material used for deicing roads. Sand cannot melt the ice, but its primary function is to add traction to the road surface that helps vehicles grip the road. As a result, sand is a better option in areas where the temperature is too cold for salt to work. Furthermore, unlike salts, it does not rust roads or contribute to environmental pollution.

Comparing sand and salt

The selection between sand and salt for deicing roads has to be taken while considering the specific situation. Sand is perfect on icy roads during the cold months when traction is more of a problem than ice. On lightly icy or snowy roads, salt can reduce the melting point of the snow, and it is then more suitable for the scenario. When using salt, it is crucial to note that it should not be used excessively because it can harm the surrounding environment.

Sand vs salt

There are specific factors that need to be considered. Such factors include temperature, the type of vehicle, location, and the anticipated amount of ice. For instance, salt is ideal for temperatures ranging from -9 to 17 degrees Celsius below these levels; sand is the better option. Additionally, it is the better choice for steep and hilly areas, as it provides a better highway grip.

Heated driveways and sidewalks

Another option for deicing is Heated driveways and sidewalks, which are expensive but highly convenient. They install heating elements under the pavement’s surface that melt ice and snow as they fall. This option requires a significant upfront investment and may require professional installation, but it eliminates the need for manual deicing and minimizes the risk of slips and falls.

Conclusion

In conclusion, sand and salt have benefits and drawbacks in deicing roadways. Both materials possess unique properties and are more suited for particular situations. The key is to choose the suitable material for the specific location, weather conditions, and other dominant factors. Therefore, road managers must assess their requirements accurately and choose the suitable material for deicing to ensure their roads are drivable and safe during winter.
