Researches on frictional properties of HDPE geomembrane using tilt table device

The essential components of tilt table device were two plates hinged together at one end.The upper plate,on which test sample was put,was continuously lifted at the free end till sample slided.The inclination of the plate was recorded.This device could measure interface frictional properties between components of lining system factually realizing the field condition of slope of landfill where normal stress was low.A simple tilt table to measure the frictional characteristics between three different HDPE(high density polyethylene) geomembranes and sand,geocomposite and woven geotextile,and the test results were presented.
