No Mess Oil Change

Many access roads in the oil patches are covered with a simple combination of crude oil and aggregate. Blade operator windrows the aggregate, spreader truck adds the crude, blade mixes it up and spreads it out. Keeps the dust down to some extent, repels water during the rainy season, lasts reasonably well. One of the local areas has a native american name, I forget the word, but it basicly means "black nasty sticky stuff bubbling up out of the ground". The "oil sand" procedure is on the politically incorrect list now so they use another substance to do the same thing and it is probably an oil derivative. Go figger.
