STABILIZATION OF A SANITARY LANDFILL TO SUPPORT A HIGHWAY

The results of the stabilization of a sanitary landfill by use of surcharges are reported. The New Jersey Department of Transportation has undertaken the construction of two experimental roadways--I-85 eastbound and I-85 westbound-- directly over landfills that contain partially decomposed garbage. Field measurements of settlement and pore-water pressure are presented. The data indicate that the settlement response of a landfill area is similar to that of fine-gained soils. Stress history plays an important role in this response. When the ratio between the stress increase caused by surcharge load and the existing stress was less than 1, the measured strain was only 5-7 percent. When this ratio was 1.4 or greater, the strain varied between 11 and 17 percent. The compression ratio for the sanitary landfill was found to range between 0.16 and 0.20. Piezometric heads were found to be erratic and frequently much higher than the projected values. This was attributed to the expulsion of methane gas from the inner piezometric tube. (Author)
