§ 91.25 SUB-GRADE.
   (A)   The work shall consist of the construction and preparation of the sub-grade on that part of the roadway intended to receive pavement and, when applicable, on sidewalks, curbs, gutters, base course, and shoulders.
   (B)   All soft, unstable, or unsuitable material which will not compact readily shall be removed and replaced with satisfactory material. All rocks and boulders shall be removed or broken off to a depth of not less than 8 inches below the surface of the sub-grade.
   (C)   All soil must be compacted so holes, ruts, or depressions will not form or develop. Compaction is extremely important to longevity of any road system.
