Houghton, Michigan, where I used to go to college, used "stamp sand",
which is actually very fine crushed rock. Think gravel, but with grains a
bit courser than beach sand.  It's all sharp edges, so it makes a great
traction material, and they have vast amounts of it from the mine tailings
piles that are everywhere up there.  The main disadvantage compared to
salt is it has to be swept off the roads at the end of the winter; it
doesn't dissolve away.
