    Remember the plan was to use this before a snow fall to aid in clearing the roads, not to remove the ice.

    I thought it was also supposed to help prevent ice from forming if sprayed ahead of time not just aid in physical snow removal.

    I've been wondering about this. I'm not arguing you at all but more thinking out loud.

    The solution is supposed to aid in the clearing of the roads presumably by melting the snow the moment it hits thereby creating less snow to remove. What I've noticed is that under mild to heavy snow fall, it turns the snow into slush which cars will drive over, but it doesn't actually really allow liquid to drain because it creates damns along the side of the road. I'm going to guess that a lot drains, but a lot also does not.

    Real life, snow falls on the solution, melts, and creates more solvent that will either run off the road because of the gradient/camber in the road, stick around and create a standing pool in odd spots, or get carried away by vehicles. Because snow will create slush when not completely melted (heavier snow fall), this will allow water to not drain off properly. Almost anyway you cut it, the solution creates more solvent with the falling snow and, more concerningly, it also creates an increasingly dilute solvent on the road. i.e. the calcium solution loses its efficacy after a certain point.

    After the solution has been diluted to the point of not being effective, what we're left with is ice.

    vs. let the snow fall sans solution and then clear it. i.e. we're not creating ice.

    I have also heard this..

    It seems like people are forgetting that this is a PILOT PROGRAM.. The city is just testing this out to determine whether it is effective or not. If it freezes and causes issues (like it did yesterday), then the city can figure out another way to combat that issue. Or.. Maybe they run this pilot and just scrap the CaCl solution.. Who knows. At least they are trying new things because Edmontonians constantly complain about our roads in the winter..

    The whole point of this is to generate less spring cleanup and damage from the sand mix and also do a better job at keeping the streets ice free.

    IMO, the roads have been much better then year then other years and also I have been to Calgary a few times this year and their roads were way worse then Edmonton and had way more ice and snow on them with the sand mix that they use.

    lest you forget, we really haven't had much snow this year.. only a fraction of what Calgary has gotten, so that's apples to oranges.

    Personally, I think the roads are worse, normally intersections where people nail the gas and spin their way up to speed was common before now 1/2 way between intersections is slicker than it was without the solution. I stopped riding my bike in the fall because the solution itself is slick, with my truck in 2wd, give it 1/2 throttle while already going 60km/h and the tires loose traction when it's 10 above... there's an issue

    Cities all over the world have tried it. Its been snowing in Canadian cities since Canada was a thing. This isn't rocket surgery, just like building the SW side of Henday out of concrete was fucking stupid and they should never have done it, this is also stupid.

    this would also be true.

    If it's like sodium chloride* it won't be effective below -18c or 0 degree's freedom ( what the goofy fahrenheit scale is based on)


    *Just looked it up, it's an ammonium chloride based scale, or it was originally.

    We've only had 3 dumps of snow this winter, 2 small ones, 1 big one... And this shit isn't working. And it's rusting vehicles. Awesome.
