Description

Damage during installation (DDI), creep and creep rupture behavior of geosynthetics have been subjected to extended studies. To contribute to the comprehension on the effect of damage during installation on the long-term mechanical behavior of geosynthetics, a research program was established. On this paper the results available for one of the geosynthetics studied are presented. This material has been subjected to field damage tests, using two different soils and two compaction energies. To characterize the effect of the damage induced in long-term mechanical behaviour, tensile creep tests and creep rupture tests were carried out, ac-cording with the procedures described in EN ISO 10319 and EN ISO 13431, respectively. The results ob-tained are compared and discussed. The main conclusions of the study are presented.
