Road Grades.
Some of our country roads in Utah have been very well constructed as far as the cross section is concerned, but no particular attention has been paid to the grade of the road in the direction of its length except when work has been done to reduce the grade on steep pitches.
Roads should have a grade or slope of about 1 to 80, or 1¼ per cent, in the direction of their length, so that water will not remain in any small ruts that may be formed, but will flow along them to a point where it will flow from the rut into the drain ditch.
