Placement was performed using various CAT dozers and one skid steer loader in a <br />one -foot compacted lift. Moisture conditioning of SLF material was performed in place using a <br />tandem -axle water truck and compaction was achieved using a 10 -ton vibratory smooth drum <br />compactor. Nuclear density testing, moisture verification, and depth check testing was <br />performed with results within project specifications. Test locations were surveyed by Ames. <br />VLF Weekly Report WE 08.20.2011 <br />
