I know that a lot of people complain about governments using salt as a way to de-ice roadways because of what the salt does to anything metal on their vehicles. In California we have been getting a lot more snowfall than usual and so snowy and ice covered roads have been getting a lot of press lately.
One of the topics discussed was why Caltrans, the state roadway maintenance division, uses sand instead of salt to increase traction on ice and snow-covered pavement. What was mentioned is that sand is used because it is causes much less damage to the surrounding environment than does salt. I guess that makes sense and I do appreciate that I don't have to continually wash and otherwise protect my motorcycles from corrosion during the winter due to the action of salt water. So I am happy about that. On the other hand, you do have to be careful when riding on sand covered roads due to the lack of traction caused by the loose sand, at least until the snowfall turns to rain and washes the sand away. I guess every approach has its pros and cons.
What do you think? Is salt a better solution to increasing traction on roads, or is sand good enough as a way to protect the environment? Personally, I have no experience riding on roadways where salt is used as a de-icer so I can only see one side of the discussion.
