within the overall grade. The horizontal alignment is consistent <br />• with the existing topography and the mine plan. The road cuts <br />were excavated in bedrock material and all slopes are flatter <br />than 1:0.25. The road embankments were constructed in lifts and <br />by routing heavy construction equipment over the lifts. The <br />embankment layers were compacted as necessary to ensure that the <br />embankment is adequate to support the anticipated volume of <br />traffic, weight, and speed of vehicles to be used for the <br />duration of the road. Compaction tests are included in Addendum <br />A, which verified that compaction exceeded 90 percent of Standard <br />Proctor and the surface appears to be stable. <br />Based on a post-construction inspection, the road appears to be <br />adequately maintained by the mine's motor grader and the road is <br />compacted from the routing of heavy construction equipment and <br />coal haulage over the road. The road structure appears to be <br />stable, evidencing no indications of cracks, deep rutting, <br />settlement, or slope instability. To the'-best of my knowledge <br />• and belief, field adjustments made during construction to the <br />structure are in conformance with the Rules and Regulations and <br />the intent of the approved design plans and specifications as <br />approved by the Colorado Mined Land and Reclamation Division. <br />JUL 13 1988 <br />Date <br />t- <br />• <br />
