A LABORATORY ASSESSMENT OF THE INTERACTION BETWEEN PEAT AND GEOSYNTHETICS

Results of simple tests using the motorized direct shear device to evaluate the interface friction between peat and selected geotextiles and geonets are presented. In order to determine the effect of testing procedure on interface friction values, test results with contact surface areas of 36, 100 and 144 sq cm, and with constant strain rates of 0.01, 0.1 and 1.0 mm/min are discussed. Test results of geotextile after 400 days of storing in peat are also given. The program of investigation also includes tests of geonet with different orientation of strands in relation to the shearing forces. The tests have indicated that the frictional resistance between geotextile or geonet and peat may be greater than in peat alone. The conclusions also show that the frictional characteristics depend on the test conditions and these should therefore be standardized. (Author/TRRL)
