A short-term model for extrapolating unconfined creep deformation data for woven geotextiles
Abstract This study reports results for creep deformation with data acquired in 72 h of testing. A system capable of performing 8 simultaneous tests was used to test four woven geotextiles of different weights, following all of the recommendations outlined in the standards related to equipment setup. A mathematical model was used to generate time-dependent creep curves for four different load levels up to 40% for each sample and using a database which presented stage II creep conditions (i.e. without rupture) through the end of the tests, up to 10,000 h. The coefficients of variation for the conventional creep tests were below 10%. The compatibility between the experimental data and the model indicates that short-term (72 h) loading tests may be used to extrapolate long-term creep deformation in woven geotextiles.
