Confined-accelerated Creep Tests on Geosynthetics
The creep behavior of geosynthetics usually characterized by standard tests which present two main concerns: they are time-consuming and may not consider the possibly significant effect of soil confinement. Several approaches have been presented in the technical literature in order to address each of these aspects, but only independently. Recently, a new apparatus was developed in order to conduct confined-accelerated creep tests using geosynthetics and both concerns were addressed simultaneously. This paper presents a new set of creep tests conducted under different conditions with the new equipment. A biaxial geogrid and a nonwoven geotextile were used in these tests, which comprised creep rupture and creep deformation ones, both in in-isolation and in-soil conditions. The results highlight the importance of both using elevated temperatures to expedite the determination of geosynthetics creep behavior and studying the effect of soil confinement in both creep test types (creep rupture and creep deformations tests).
