Will snow plowing affect the pavement? What about salt?

Snow plowing has the potential to damage the pavement but this can be minimized if you use a rubber blade on the plow and exercise caution. Obviously, the type of stones will make a difference too. Harder stones such as marble and granite will be more durable. Softer stones are going to be more vulnerable. A snowblower would be a safe machine to use. Additionally, it is completely safe to apply salt for melting ice and snow.
