The equipment being used was a John Deere 245G LC Excavator, a Volvo SD75B Soil Compactor, and proof rolled with a CAT 972H Wheel Loader. Approximately 28 inches of existing pit run was being removed in the area of the new batch plant to create the base for the foundation. After the material was dug to the required grade the soil compactor made a minimum of 4 passes over the entire pad. Two areas were determined to be soft and pumping while under a load due to over moist material. One area was on the north center side of the pad, and the other on the south west corner. The areas in question were over excavated, suitable material was placed and compacted to replace the pumping material. Once repairs had been completed a proof roll was made over the entire pad with minimum movement.
