In the winter we take for granted, passing on the cleared and dusted sidewalks and resents sluggishness of public services, getting stuck in traffic during a snowfall, knowing full well that we demand the impossible. And be sure to choose the appropriate epithets, seeing white stains traces "of anti-treatment" on his shoes and pants. Winter – season testing for road construction. Cleaning and snow removal, maintenance of the roadway and clean, with enough high adhesion. None of this is simple – to provide for continuous heavy traffic and very time-consuming. Add to this a rather limited room for maneuver forces and means. Yes, and green always require restriction or prohibition on the use of certain chemicals, and mechanical cleaning to cope with mountains of snow on the roads, not paralyzed traffic in the city impossible. So what utilities treated with the sidewalks and roadway, and that such anti-icing agents (GMP).
How it works, both positive and negative consequences of such treatment. The most common and familiar to all means of dealing with winter icy roads is a common sand. However, the reagent in pure form, it can not be named, most effective material for anti-icing, but in a mixture with at least the same salt get a good CP. Use a mixture of sand and the salt started with 60 of the last century. The cheapest way to deal with icy roads. However, not without flaws. Sand accumulated over the winter in large numbers, turning the streets into a dirty mess, and in the spring of all this washed into the drainage system, tightly clogging drains.
