Behavior of Seepage Control Liner under Snow Weight

Abstract

Snow weight takes an important role in a cold area on maintaining its facility of a seepage control liner for a long period of time. However, there isn't enough data accumulated relating to the behavior of seepage control liner under snow condition and cold temperature. We had a chance to measure its behavior of a seepage control liner at the prototype test field. Its conditions are divided into two types of slopes. Each of which covered respectively by the two different structures of liners. The one of them consists of unwoven textile and seepage control liner, and the other consists of covering soil, unwoven textile and seepage control liner. The deformations of liners are targets to measure that caused by temperature under snow weight. In the same manner, the deformation of high dense polyethylene and the low dense produced by using metallocene catalyst was measured under the outside temperature. These results are shown in this paper.
