• There are virtually no road cuts on this haul road section. It is constructed on grade in <br />the valley floor. The relocated section of haul road will also be constructed on the <br />valley floor. For the relocation of the haul roads on site, all vegetation material and <br />topsoil will be removed from the design road bed, shoulders, and surfaces where <br />associated structures will be placed. Topsoil will be placed in the topsoil stockpile. Nc <br />vegetation material or topsoil will be placed beneath or in any haul road embankment. <br />Construction <br />The following embankment specification applies to road sections not within the <br />disturbed area in accordance with Rule 4.05.2(4). In the placement of embankment for <br />the haul road, materials will be spread in layers approximately 12 inches deep, and <br />such lifts made uniformly over long stretches and for the full width of the embankment. <br />Each lift will be moistened or dried to a uniform moisture content suitable for maximum <br />compaction. Hauling equipment will be routed both ways over the fill and routing varied <br />sufficiently to achieve uniform compaction. Compaction will be carried to the edge of <br />the fills so that the final slopes are firm. A sheepsfoot roller or other suitable equipment <br />may be required to achieve compaction. Compaction of each lift will continue until the <br />• unit dry weight of the lift reaches a value not less than 90% of maximum unit dry weight <br />attained in a laboratory compaction test in accordance with the specifications of ASTM <br />D 698, Method D. <br />Where the embankment is placed against the existing slopes, the slopes will be <br />benched and scarified down to a firm dense base as the new fill is being placed. <br />Material so loosened will be mixed with the new fill and the resultant mix blended firmly <br />into the slope. <br />When rock or rocky material is used for embankment, placement shall be in layers not <br />exceeding the maximum size of the rock present, and in no case shall lifts exceed 30 <br />inches in depth. Rock layers shall be compacted by routing the spreading equipment <br />and loaded hauling equipment over the entire width of the fill until compaction is <br />obtained. <br /> <br />M" 2.2-Iii 9/02 <br />
