Road cut and fill involve the haulage, placement, and compaction of suitable road fill material (road base) over the entire width of the road as follows: 1) Where there is more than 5 feet of fill, the top 5 feet will be compacted to 95 percent of American Association of State Highway and Transportation Officials ( AASHTO) T -180, with the remainder compacted to 90 percent AASHTO T -180; 2) Where there is a minimum of 3 feet, but less than 5 feet of fill, the entire fill will be compacted to 95 percent of AASHTO T -180; and, 3) Where the road is in a cut, the roadway will be over - excavated and a 3 -foot minimum thickness road fill placed and compacted to 95 percent of AASHTO T -180. Moisture content and compaction will be monitored during construction. A 12 -inch gravel base will be spread and compacted to 95 percent of AASHTO T -180, followed by spreading and compaction of 6 inches of gravel surfacing to 95 percent of AASHTO T -180. Typical road surfacing characteristics will conform to the following specifications: Screen Size Material Passim 1 -% inch 100% 1 inch 75 -90% 3/8 inch 40 -75% No. 4 mesh 30 -60% No. 10 mesh 20 -45% No. 40 mesh 15 -30% No. 200 mesh* 5 -15% *The faction passing the No. 200 mesh shall not be greater than two - thirds of the fraction passing the No. 40 mesh.
