What is one advantage of using pre-wetted salt?

Using pre-wetted salt is advantageous because it reduces salt usage. When salt is pre-wetted, it typically allows for better adherence to the road surface and enables faster melting of ice and snow compared to dry salt. This increased effectiveness means that less salt is needed to achieve the same level of de-icing, leading to cost savings and a lower environmental impact. By using less material, municipalities can also help reduce the potential for salt runoff into waterways, which can be detrimental to local ecosystems.

The other options do not present valid advantages for pre-wetted salt in the context of its use in public works. Deterioration rates, aesthetic aspects, and storage requirements are not primary objectives or benefits of pre-wetting salt for winter maintenance activities.
