§4.03 Roads <br />(vi) Not applicable. <br />(vii) In the placement of embankment for the haul road, materials <br />will be spread in layers approximately 12 inches deep, and <br />such lifts made uniformly over long stretches and for the full <br />width of the embankment. Each lift will be moistened or dried <br />to a uniform moisture content suitable for maximum <br />compaction. Hauling equipment will be routed both ways over <br />the fill and routing varied sufficiently to achieve uniform <br />compaction. Compaction will be carried to the edge of the fills <br />so that the final slopes are firm. A sheepsfoot roller or other <br />suitable equipment may be required to achieve compaction. <br />Compaction of each lift will continue until the unit dry weight of <br />the lift reaches a value not less than 90% of maximum unit dry <br />weight attained in a laboratory compaction test in accordance <br />with the specifications of ASTM D 698, Method D. No records <br />of compaction tests or as-constructed moisture content tests <br />are available on the existing train loadout haul roads. <br />(viii) See vii above. <br />(ix) Embankment slopes do not exceed 2h:1 v at the existing train <br />loadout haul roads. <br />(x) Temporary erosion control measures will be implemented <br />during the construction of new haul roads. Straw bales or other <br />alternative sedimentation control devices will be placed along <br />the edge of the embankments. Immediately after construction <br />is complete the area disturbed will be seeded and mulched to <br />promote a reduction in the rate and volume of run-off. <br />(xi) If any further disturbance is required for haul road construction, <br />topsoil will be handled removed and stored in accordance with <br />4.06.3. <br />Ir <br />TR-20 4.03 - 4 3/01 <br />
