    Wpływ cyklicznego nasłoneczniania na przebicie statyczne wybranych geosyntetyków
    (Wydawnictwa AGH, 2011) Cholewa, Mariusz; Lupa, Marcin
    The paper presents results of tests of the static punch strength of chosen geosynthetics subjected to cycles of insolation amounting to 100 hours. Three geotextiles (GW-1: of knitted continuous filaments, GW-2: of welded continuous filaments and GW-3: of stitched continuous filaments), three geonets (GS-1: of the density of 16 openings per 1 cm2, GS-2: of the density of 1 opening per 1 cm2, GS-3: of the density of 1.0 openings per 1 cm2) and three geomembrans (GM-1: 0.3 mm thick, GM-2: 1.0 mm thick and GM-3 1.5 mm thick,) were used for the tests. The tests of punch shear were conducted in accordance with a method described in the standard PN-EN ISO 12236. For each of the nine materials, the results of tests of so called »fresh« and insolated samples were compared. It was shown that the influence of solar radiation received during 100 hours do not cause weakening geonets and geomembrans. It were only geotextiles that showed decreasing of strength value.
