Abstract:

A double liner system is required in hazardous waste disposal facilities to satisfy the current Resource Conservation and Recovery Act and State of Michigan Act 64 Requirements. To meet these requirements, a design of five feet of compacted clay between multiple layers of geosynthetics was developed. The double liner system consists of a composite primary liner made of a geomembrane plus 5 feet (1. 5 m) of compacted clay, and a secondary synthetic liner. A leak detection system made of a drainage fabric overlying a drainage net is placed between the two liners. Because of concern over the stability of the compacted clay layer on the side slopes and the possibility of damaging the geosynthetics during the clay compaction operations, a test fill was constructed using the materials, construction equipment, and methods intended for use in the construction of the actual cell.
