**MathMate**, Tuesday, November 15, 2011 at 3:30pmAccording to the rule, a 100% grade rises 100 feet for every 100 feet of horizontal run. This makes a 45° angle with the horizontal.

Cars cannot drive up that slope, nor trucks. For someone to walk on it, it requires the friction. I managed to walk on a shingled roof of 40° on running shoes (so they don't slip) but it was not easy.

Yes, it is possible to have a grade of more than 100%, but probably not for a useful road.
