Salt is awful. It ruins your car, and even if it melst ice at -4 degrees celsius, it only levels it out so it becomes a hockey rink when it turns -14 (C) in the night. Then you can hardly even walk on it. Gravel is a better pick.
Wow. OK, with that one paragraph, you just lost all credibility with me, with respect to winter driving.
I live in Canada. Trust me, I know winter driving. Every year, we drive to my family's home at Christmas. This is a 1,300 km drive, from Ontario to Nova Scotia, so I'm crossing through 4 provinces. 3 of them salt their roads (Ontario, Quebec, Nova Scotia), and one uses sand instead (New Brunswick). The drive through New Brunswick terrifies me.
Sand is USELESS
in bad winter weather. All it does is makes the snow dirty. It's horrible. I cannot express strongly enough how pathetic it is, compared to salting the roads.
Salt is effective down to -20, not -4 as you erroneously state. And the melted snow/ice doesn't just sit there, waiting for it to get cold enough for it to refreeze again. It's constantly getting thrown up into the air as vehicles drive over it, which vaporizes it and causes it to go away. Eventually, the road ends up dry. Sure, there's a little salt residue, but I'll take dry pavement with a thin film of salt over a road covered in sandy snow any day.
Besides, even if it did "refreeze overnight when it drops to -14" as you claim, surely you understand that during the DAY, while the show is melted by the salt, is when the vast, vast majority of vehicles need to use the road anyway, right? Who cares if the road is a sheet of ice at 3:30 AM (besides the one poor guy driving on it)? As long as it's clear during rush hour, when 200,000 cars pass over it, isn't that a worthwhile tradeoff?
Northern Light, some of the things you're posting on this thread make me wonder if you're trolling. It's absolutely nonsensical.
