Salt does not always melt the ice and snow on a road. If real salt (sodium chloride) is being used, the temperature where the salt contacts the ice and snow must be 20 F or higher for it to cause melting. On well traveled roads, the friction from the tires on the road can produce those conditions even if the temperature in general is notably lower, but there will come a temperature, especially in more northern locations, where salt will not work.
There are salt substitutes for melting snow and ice, and they work at lower temperatures. Nevertheless, temperatures can drop low enough that even they won't work.
That is one reason that highway departments often spread sand before salt or together with salt. The sand helps tires develop friction and hold the road on packed snow, and also absorbs sunlight, increasing the temperatures in the mix on the road.

Can pool salt melt icy roads?
for sure
Why is rock salt used on icy roads and not road salt?
Rock salt is used on icy roads because it has larger granules that are more effective at providing traction. Road salt, which is a finer grain, is more commonly used to melt ice and snow on road surfaces. Rock salt is also less expensive and more readily available.
What do you put on a road when it snows?
Salt or a mixture of salt and sand is typically placed on roads when it snows to melt the ice and improve traction for vehicles. Sand alone can also be used to increase traction on icy roads.
Why does salt sprinkle on ice roads cause ice to melt?
Sprinkling salt on icy roads doesn't warm up the ice. What it does is depress the freezing point of water to the point where the ice is too warm to be solid, even though it is just as cold as before.
What rock or mineral is used to melt ice on streets and sidewalks?
In the UK, it is known as rock salt. The rock salt (the dried remains of ancient seas) is an underground deposit of salt that is mined and used to grit icy roads and pavements.
Can pool salt melt icy roads?

What to put on icy roads?
It is recommended to use salt or sand to increase traction on icy roads. Sand provides grit and improves grip, while salt helps to melt the ice. It is important to drive cautiously and slowly on icy roads to prevent accidents.

Why do people put salt and sand on the road what do they do individually?
Salt is used to melt ice by lowering the freezing point of water, making it easier to remove. Sand is used for traction on icy roads to improve tire grip and reduce the risk of slipping. Together, they help improve road safety during icy and snowy conditions.
How do they get salt for icy roads out of a freshwater lake?
The salt used on icy roads in winter is quarried from underground salt deposits (salt mines), which are the remains of ancient salty seas. Salt is not extracted from fresh water.
Why does salt sprinkle on ice roads cause ice to melt?
Sprinkling salt on icy roads doesn't warm up the ice. What it does is depress the freezing point of water to the point where the ice is too warm to be solid, even though it is just as cold as before.
Why do you use salt on the icy roads?
Adding salt the freezing point of water is lowered.
What rock or mineral is used to melt ice on streets and sidewalks?
In the UK, it is known as rock salt. The rock salt (the dried remains of ancient seas) is an underground deposit of salt that is mined and used to grit icy roads and pavements.
Does salt stop ice from melting?
Salt does not stop ice from melting; rather, it lowers the melting point of ice. When salt is added to ice, it disrupts the equilibrium between ice and water, causing the ice to melt at a lower temperature than 0°C. This can be useful for preventing ice from forming on surface areas, but it will ultimately lead to the ice melting more quickly.
Why does salt sprinkled on icy roads cause the ice to melt?
Sprinkling salt on icy roads doesn't warm up the ice. What it does is depress the freezing point of water to the point where the ice is too warm to be solid, even though it is just as cold as before.
Why do people use salt on icy roads?
because it will melt the ice on the sidewalks.
