Creep of Geotextiles Using Time–Temperature Superposition Methods

Abstract

The objective of this study is to evaluate the creep deformations, creep failure, and residual tensile strength of geosynthetics using accelerated time-temperature procedures and procedures consistent with rapid tensile testing. The study proposes new definitions for the quantification of creep, of creep failure, and of the reference strength for quantification of residual strength. Design implications are proposed regarding the use of creep reduction factor to account for the actual loss in tensile strength after sustained creep while still accounting for creep.
