Yes wood shavings are awesome I carry a bale in my truck incase some one is stuck, works far better than kitty litter or sand.When it's half-3/4 frozen, toss some gravel, kitty litter, sawdust, wood shavings down it so it sticks out of the frozen stuff: traction. Don't worry about salt. If the temp drops below 25F, it's useless anyway.
I also use old horse bedding for my walkways, and around the horses paddocks. I once made the mistake of using the road sand/salt mix used by the roads dept here. The horses ended up licking up the mixture
