Lately they have been using Brine around the NY, NJ area.

I've heard that but brine is just water and salt. Not sure what the
advantage of that when it's too cold for salt to work at all.

Around here they put brine on the roads well before it snows/sleets. The
brine dries and then when the moisture hits it liquefies again and keeps the
snow from sticking. Followed up with salt after there is some accumulation,
combined with traffic churning the slush and the ice doesn't have a chance
to form. The prophylactic application of salt brine seems to work really
well and saves money much like another type of prophylactic saves money on
child rearing... ;~)
