RESUMO

This work presents results of creep tests on no woven geotextiles tested in confined lab tests. In the used equipment, the reinforcement is confined between two soil layers, allowing both materials to have freedom to deform with time. In those tests, a vertical stress is applied to the soil that transfers load to the reinforcement. The tests were performed using three no woven geotextiles, two of polypropylene and one of polyester, and four types of confining soil: three granular materials and sandy silty clay. Besides, unconfined creep tests were carried out to allow comparison with the confined tests. The results indicated that there was great contribution of the confinement in the reduction of the creep deformations of the tested materials. Also the influence of some factors was evaluated in the confined creep of the no woven geotextiles, such as: soil type, type of geotextile and mass per unit area of the reinforcement. Such results allow the evaluation of the potential of creep of the system soil-geotextile
