Bulldozers will be used for short pushes with scrapers <br />handling material which must be conveyed longer distances. Water trucks <br />and graders will be used for finish work and continued maintenance. <br />3.5.9 CON9TAUCTION MSTHOD9 <br />Roads will be designed for safe use by maintaining the lowest possible <br />gradient without use of switchbacks or hairpin turns. The majority of new <br />roads constructed are built on spoils, with the exception of one light use <br />road on natural ground. <br />The light use road is used to access Trout Creek for obtaining water <br />• for dUSt control. The final placement of the road has been field designed <br />and was dependent upon the as-built configuration of the sedimentation <br />pond and on-site topography. The filial design and construction was <br />performed in accordance with CMLRD Rule 4.03.3(3). Since this road is <br />designed to cross the north diversion ditch, a riprapped low water crossing <br />will be maintained at the crossing location. The location of this road is <br />shown on Exhibit 3.5-1. <br />The location of all haulage, access and lighty use road corridors are <br />shown on Exhibit 3.5-1. A complete description of all roads is provided in <br />Section 3.6.2.1. <br />Haulroad and access road construction begins after the centerline and <br />slope of the roads are surveyed and marked. Bulldozers and scrapers create <br />the cuts and fills required to bring the road to the design grade. The <br />materials used as fill will be void of coal or vegetative matter. <br />Compaction of fills vary in accordance with lift thickness. At final <br />grade, haulage and access roads are compacted using equipment that exerts <br />high-bearing pressure. Soft areas in the road bed are removed, refilled <br />and compacted until a substantial road base is created. Roads are <br />. surfaced, crowned and recompacted. All haulroads and access roads are <br />Mid-term '99 3.5-1 September 15, 1999 <br />
