Can you salt asphalt?
In fact, salt doesn’t affect asphalt until it is already in a state of advanced deterioration. Potholes are caused by water that has entered into the ground under the pavement. While salt has the potential to exaggerate the freeze-thaw cycle, it is not the root cause of potholes.
What is the best salt to use on a driveway?
Magnesium chloride is a great choice! While magnesium chloride is more expensive than sodium chloride and calcium chloride, it is less likely to damage your concrete or your lawn. This type of salt only works in temperatures down to 0° F, which is better than sodium chloride but not quite as good as calcium chloride.
