Creep Response of Untreated and Additive Treated Jute Geotextiles in Isothermal Condition
Abstract Similar to geosynthetics, Jute Geotextiles (JGTs) also show different load-strain–time responses under different loading regime at isothermal conditions. For JGTs strain envelope approach through isochronous curves is adopted, which is already being implemented for geosynthetics. The required parameters of JGTs for ultimate strength design approaches are rarely reported in literature. JGTs shows significant amount of strain difference at the very beginning and has small fluctuation over time compare to synthetic geotextiles. From isochronous curves of selected JGTs, the possible design life for a particular load or the load carrying capacity at the End of Design Life can be predicted for a specific strain. Strain envelops show that locked strain ($ Ɛ_{L} $) increases from 7.1 to 8% for time period of 0.1 h to 100000 h and the recoverable strain ($ Ɛ_{R} $) decreases with the increase in loading time. Results indicate that when a particular strain is developed within a shorter duration, larger value of $ Ɛ_{R} $ and smaller value of $ Ɛ_{L} $ are found. In case of longer duration, it vice versa. The available strain ($ ε_{R} $ = $ ε_{T} $—$ ε_{L} $) indicates the capability to withstand additional short-term loads e.g. earth quake, which decrease proportionally with the increment of $ Ɛ_{L.} $ With this understanding it can be said that the overall system became vulnerable against additional loading over ages whereas the total strain remains same. It is expected that the findings and observations of the study will be useful for the application of JGTs in various civil engineering works, as well as for the standardization of JGTs.
