Abstract
The creep characteristics of geotextiles under sustained load are important for their satisfactory performance in civil engineering. In this paper, series of laboratory creep tests are carried out and typical test results are given for some wovens and nonwovens. They indicate that creep resistance of needle-punch nonwoven and multi-filament woven are larger than heat-bond nonwoven and mono-filament woven made from polypropylene. Also the test results are analyzed to investigate their creep parameters based on emprical creep equation for soils developed by J. K. Mitchell. The parameters obtained from the analyze are almost equal to the soil's one.
