Abstract
A test fill was constructed over a closed, industrial waste landfill located in southeastern Michigan. The objective of this test fill was to evaluate the immediate and time-dependent response of the existing landfill to an increase in load. The closed landfill contains a widely varying mixture of non-hazardous industrial wastes such as foundry sand, ash, and wastewater treatment sludge. It also contains construction and demolition debris. The surface of the landfill is relatively flat and, at the site of the test fill, is underlain by approximately 30 feet (9.1 m) of waste, some 15 feet (4.6 m) of which is saturated. Native clay till underlies the closed landfill and is approximately 8 feet (2.4 m) thick. A fractured, relatively non-weathered limestone underlies the till. The test fill was comprised of approximately 5000 cubic yards (3,800 m3) of clay and was 12 feet (3.7 m) thick at its peak. The size at the base was approximately 160 feet (48.8 m) by 140 feet (42.7 m). The settlement of the existing landfill surface beneath the test fill was monitored with three laterally-distributed settlement points. Settlement of up to 0.5 feet (0.15 m) occurred concurrent with imposition of the increased load. On completion of the test fill construction, the settlement pattern became linear with the logarithm of time. From this data, load-dependent and time-dependent compression characteristics were estimated for the in-place industrial waste.
