Previous subgrade acceptance is <br />shown on Figure 1. <br />B) Slope Contouring <br />1) VLF <br />Slope contouring was performed between stations A11 +00 ( + / -) and A15 +00 ( + / -), <br />approximately 0 to 300 feet right of centerline. Slope contouring was performed using two <br />CAT D -6 LGP dozers. <br />C) Soil Liner Fill <br />1) VLF <br />Soil liner fill (SLF) placement continued in the areas shown on Figure 2. Subgrade was <br />approved and moisture conditioned prior to placement using a tandem -axle water truck. <br />Placement was performed using various CAT dozers and one skid steer loader in a one -foot <br />compacted lift. SLF material was hauled to the placement area from the S. Cresson clay <br />stockpile using 40 -ton articulating haul trucks loaded by a John Deere 744 front -end loader. <br />Moisture conditioning of SLF material was performed in place using a tandem -axle water truck <br />and compaction was achieved using a 10 -ton vibratory smooth drum compactor.
