Evaluation of an existing composite cover over steep landfill slopes
The paper presents the results of an evaluation of the stability and hydraulic performance of a landfill cover built over 2.5 horizontal to 1 vertical (2.5H:1V) sideslopes. The evaluation consisted of excavating a section of the cover, and testing a geosynthetic clay liner and a compacted clay liner. The purpose of the evaluation was to assess the performance of the cover after three years of service. Data are presented on the moisture content and internal shear strength of the GCL, and the moisture content and hydraulic conductivity of the compacted clay layer. Test results indicate that the internal shear strength of the GCL has not degraded, and that the cover is stable with an acceptable factor of safety. The cover has not visibly weathered, deteriorated, clogged or shown evidence of slippage. The clay layer has not dried or exhibited a substantial increase in hydraulic conductivity.
