roads recently oiled

On unpaved country roads initially the dirt floor is leveled, pot holes
filled with gravel, and then crushed rock or gravel is spread over the road;
if there's enough warrent to do so a steam roller presses the rock or gravel
into the dirt floor, or the weight of traffic is used to compress the road.
Then as a final step, and occasionally when dust is a problem, a layer of
oil--often discarded engine oil from oil changes--is applied; often, if the
traffic requires it, macadam is applied over this "old road" to bring it up
to a more civilized standard.

If you happen to drive on a pebble-and-oil road, the purchase of kerosene
(aka "coal oil") and a lot of rubbing is needed to remove the gelatinous
mess on your tires and fenders.
