Slope contouring was performed using various dozers. A CAT <br />smooth drum roller was used to compact finished slopes. <br />C) Cut to Fill <br />1) VLF <br />A CAT 385 excavator was used to excavate material from a designated area in the Cresson pit. <br />The material was loaded into CAT 777 haul trucks and hauled between stations A54+00 (+/-) <br />and A57+00 (+/-), approximately 0 to 50 feet left of centerline and between stations K8+00 <br />(+/-) and K11+00 (+/-), approximately 200 to 220 feet left of centerline. Structural fill was <br />placed in 18" to 24" lifts using various CAT dozes. Each lift was moisture conditioned using a <br />CAT 773 water truck (when necessary) and compacted using a 10-ton vibratory smooth drum <br />VLF Weekly Report WE 09.11.10.D
