Cold temperature testing of geotextiles: new, and containing soil fines and moisture

摘要

ABSTRACT: A test program examined the behavior of geotextiles at very low temperatures, andntested the hypothesis that the presence of soil fines and moisture would result in decreased strengthnvalues compared with geotextiles at cold temperatures. Wide-width strip tensile and static puncturentests were performed on needle-punched nonwoven polypropylene geotextiles at 208,08, u0001208, u0001408nand u0001548C for the wide-width strip tests and at u0001518C for the puncture tests on new specimensnand specimens that contained soil and moisture. At all sub-freezing temperatures, the specimensnthat contained ice and soil were much stronger and more brittle in tension than the new specimens.nSoil and moisture did not significantly influence puncture strength.
