I've often thought that would be a good way to handle secondary roads here in NH. Plowing and salting to get back to bare pavement seems to be very wasteful. With snow tires there is an amazing amount of traction on packed snow. We have plenty of dirt roads around and they don't usually get plowed back to dirt, and they are fine to drive on. I imagine we could extend that to other roads as well.
I asked my mom about this, and she remembers in the early 30s taking a sleigh to church on Sundays (memorable because the children were allowed to ride the back runners on the way home).
She says she never saw a "snow roller" (this was Minnesota) but that it would have made sense in the era of sleigh traffic, when you wanted snow on the roads in winter, not gravel.
Snow pack is the safest stuff to drive on in winter.
Salting and plowing to bare roads only works when it works... but usually it doesn't. Even if the weather cooperates you get snow drifts that cross the roads sometimes. And when the snow keeps coming, you just get a mess of changing road conditions, snowy wet slick icy dry, and everything in between.
Much better to have a consistent surface. Then your stopping distance and traction don't keep changing constantly.
Eric Sloane illustrated a snow roller in one of his books. He mentioned that winter was the time to move heavy loads, using ox-drawn sleds on compacted snow -- it was much easier than driving wheeled carts in the ruts. Snow was actually shoveled onto covered bridges so that sleds and sleighs could cross. The compacted snow made travel and hauling so much easier!

ReplyDeleteInteresting. It certainly makes sense.
