AN EXPERIMENTAL HIGH-ASH PAPER MILL SLUDGE LANDFILL

An experimental high-ash paper mill sludge landfill was constructed and monitored over a two-year period to obtain engineering data essential for development of guidelines for the design and operation of future solid paper mill waste landfills. Conventional consolidation tests on undisturbed field samples gave void ratio vs. logarithm of pressure relationships suitable for prediction of ultimate primary settlements. Rapid primary compression suggests that preloading can be an effective method for stabilization and minimizing long-term settlements. The increase in shear strength associated with sludge consolidation produced a stable 3:4 slope. As planned, a 1:8 slope failed 4 days after excavation. A slope stability analysis using vane shear strengths gave excellent agreement between the predicted and actual factor of safety. /Author/
